Migrating to Etendo (from Openbravo)

Overview

This guide provides the necessary information to migrate an existing Openbravo instance to a new Etendo instance (in its latest release).

Requirements

Before the migration process begins, either if it is done on Linux or on Windows, make sure to have the following items:

Info

  • Current Openbravo instance updated to 21Q3.2 (How to upgrade?)
  • If previous installation had custom patches applied, they must be ready to be applied in an 21Q3.2 updated environment.
  • Database should not have local changes.
  • Enough disk space for new installation.
  • Environment license and GitHub name and token (Create the credentials by following this guide).

Warning

  • The server where the database is hosted needs to have enough free space to hold a copy of the current database.
  • The server where the sources are hosted also needs to be able to hold a copy of the current sources.
  • Attachments are kept in the same place as they were before.

Instructions for the Migration Process

Before starting the migration

It is necessary to ensure following the next steps:

  1. Stop the Tomcat Server.

    Terminal
    sudo /etc/init.d/tomcat stop

    Info

    Depending on your server, this command may need to be changed.

  2. Create a backup of your instance.

Manual Migration Process

These are the steps to follow for the manual migration from OpenbravoERP to Etendo Classic:

  1. Create and enter the folder Etendo Classic.

  2. Insert the etendo_base sources in the Etendo Classic folder. They can be extracted after downloading Etendo from Resources. To do this, use your gitHub user and token.

  3. The gradle.properties file has default params but if needed this can be changed.

    Note

    Remember to set up the GitHub user and token since they are used to expand private modules. Create the credentials by following the Use of Repositories technical guide.

    gradle.properties
    githubUser=
githubToken=

context.name=etendo

bbdd.sid=etendo
bbdd.port=5432
bbdd.systemUser=postgres
bbdd.systemPassword=syspass
bbdd.user=tad
bbdd.password=tad

    Info

    Check if it is necessary to keep the Openbravo database or create a new one for Etendo. In case of creating a new one, use the previous Openbravo one as a base.

  4. In a new terminal opened in EtendoERP folder, run in the

    Terminal
    ./gradlew expandCore

  5. Run in the terminal
    Terminal
    ./gradlew setup

  6. Move the existing modules from Openbravo/modules folder to the EtendoERP/modules folder, except for the following ones:

    Warning

    com.smf.securewebservices
    com.smf.smartclient.boostedui
    com.smf.smartclient.debugtools
    org.openbravo.advpaymentmngt
    org.openbravo.apachejdbcconnectionpool
    org.openbravo.base.weld
    org.openbravo.client.application
    org.openbravo.client.htmlwidget
    org.openbravo.client.kernel
    org.openbravo.client.myob
    org.openbravo.client.querylist
    org.openbravo.client.widgets
    org.openbravo.financial.paymentreport
    org.openbravo.reports.ordersawaitingdelivery
    org.openbravo.service.datasource
    org.openbravo.service.integration.google
    org.openbravo.service.integration.openid
    org.openbravo.service.json
    org.openbravo.userinterface.selector
    org.openbravo.userinterface.skin.250to300Comp
    org.openbravo.userinterface.smartclient
    org.openbravo.utility.cleanup.log
    org.openbravo.v3
    org.openbravo.v3.datasets
    org.openbravo.v3.framework

    These modules will already be in the EtendoERP/modules_core folder since they are core modules in Etendo.

  7. Run

    Terminal
    ./gradlew update.database compile.complete.deploy --info

Info

Compilation errors associated with API changes may occur due to the version change in custom modules. If this happens, make sure to fix them by using the documented GitHub issues.

Post Migration Configuration

Remove previous instance deployed context

Terminal
rm -r /var/lib/tomcat/webapps/openbravo

Warning

Make sure this step is done before starting Tomcat, otherwise you will risk having two environments running at the same time, which can cause problems (especially when background processes are involved).

Start Tomcat

Info

Depending on your server, this command may need to be changed.

Terminal
sudo /etc/init.d/tomcat start

Attachments Configuration

Warning

Before removing your previous instance, make sure you migrate your attachment files.

In the migration process, the attachments directory configuration is not changed. To move them to a new folder (for example /opt/EtendoERP/attachments), you must edit the Openbravo.properties file:

Terminal
vi /opt/EtendoERP/config/Openbravo.properties
## Change the attach.path property like this (do not include the #):
## attach.path=/opt/EtendoERP/attachments

and move the attachments manually:

Terminal
mv /opt/OpenbravoERP/attachments /opt/EtendoERP/attachments
## Deploy changes to tomcat
./gradlew smartbuild

Info

Special consideration may have to be taken into account if your attachment folder is in a network drive, or a different partition (with or without a symbolic link in place).
Be careful when changing the attachment configuration, and make sure you have a recent backup available.

Customizations to Core

Reapply patches to core if necessary, and compile.

Info

Compilation tasks now can be made with the Gradle Wrapper.

Terminal
patch -p1 < customPatchToCore.patch
## Apply other patches as needed
./gradlew smartbuild
sudo /etc/init.d/tomcat restart

Apache Configuration

  1. If necessary, change apache configuration to use jkmount in the correct context ("openbravo" by default in old installation).
    Configuration file should be in /etc/apache2/conf-enabled/openbravo.conf, /etc/apache2/conf-available/openbravo.confor /etc/apache2/sites-available/000-default.conf / /etc/apache2/sites-available/000-default-le-ssl.conf
    Replace jkMount /openbravo* ajp13_worker by jkMount /etendo* ajp13_worker

  2. Change apache configuration to redirect to new context ("openbravo" by default in old installation).
    Configuration file should be in /var/www/html/index.html.
    Replace <META HTTP-EQUIV="Refresh" CONTENT="0; URL=openbravo"> by <META HTTP-EQUIV="Refresh" CONTENT="0; URL=etendo">

    Warning

    Make sure to replace by the context you chose when in the gradle.propertiesfile.

  3. Restart apache:

Terminal
sudo service apache2 restart

Activate your instance

  1. Login as System Administrator and use the Instance Activation window to activate your instance.
  2. Use Refresh Online
  3. Enter your instance purpose and your activation key.

Success

Your instance is activated!

Change backup and restore script

  1. Make sure that the backup script now obtains its data from the correct Openbravo.properties, for example in folder /opt/EtendoERP/
    The backup script is usually located in /usr/share/openbravo/backup/backup. You should change the lines to point to the actual Openbravo.properties file. For example:

    Terminal
    db_login=$(awk -F = '/^bbdd.user/ {print $2}' /opt/OpenbravoERP/config/Openbravo.properties)

    Should be changed for something like this:

    Terminal
    db_login=$(awk -F = '/^bbdd.user/ {print $2}' /opt/EtendoERP/config/Openbravo.properties)

    This will vary depending on the path that has been selected for the migration.

    Warning

    Remember that in the current state Openbravo.properties does not change its name. This should not be changed until further notice from the development team. Also, you must not change the Openbravo name anywhere else. Do it only in the paths for the properties file.

    Info

    A dedicated backup tool is in development.

  2. The same should be done for /usr/bin/openbravo-restore. Given that the scripts are highly hardcoded, you have to change some lines manually.

The database to be dropped should be the Etendo database, but the script will drop the openbravo db. This should be changed to drop the Etendo database.

  • Change:

    su - postgres -c "psql -U postgres -c "drop database openbravo"" || true

    for: 

    su - postgres -c "psql -U postgres -c "drop database etendo"" || true

  • Change the line that creates the database:

    su - postgres -c "psql -U postgres -c "create database openbravo WITH ENCODING='UTF8' OWNER=TAD;""

    for

    su - postgres -c "psql -U postgres -c "create database etendo WITH ENCODING='UTF8' OWNER=TAD;""

  • Change the target database on the lines that the pg_restore is done, for example:

    PGPASSWORD=tad pg_restore -U tad -h localhost -d openbravo -O $TEMP_FOLDER/db_backup.dmp || true

    for

    PGPASSWORD=tad pg_restore -U tad -h localhost -d etendo -O $TEMP_FOLDER/db_backup.dmp || true

  • Change the line which erases the tomcat files:

    rm -rf /var/lib/tomcat/webapps/openbravo || true

    for

    rm -rf /var/lib/tomcat/webapps/etendo || true

  • Change the path of the sources for the new path created for Etendo, for example:

    sudo chown openbravo:openbravo /opt/OpenbravoERP/

    for

    sudo chown openbravo:openbravo /opt/EtendoERP/

Warning

The same warning for the backups applies here. Be careful with what you rename. If you see an error, please ask for support.

Change initial directory on login

Inside ~/.bashrc you may have a command that lets you log in directly to the /opt/OpenbravoERP folder. Change it so it points to your new instance folder:

.bashrc
## Change
cd /opt/Openbravo
## To
cd /opt/EtendoERP

Change server user

You may change the current user from Openbravo to Etendo, if you want. This guide does not cover how to do so.

Remove previous installation

  1. Remove Openbravo context from Tomcat folder:

    Terminal
    rm -r /var/lib/tomcat/webapps/openbravo

  2. Remove Openbravo installation:

    Terminal
    rm -r /opt/OpenbravoERP

  3. Remove Openbravo database:

    Terminal
    psql -h localhost -U postgres -d etendo -c "DROP DATABASE openbravo;"

Warning

Make sure above commands are pointing to the correct databases, user and host, and that you have done a backup before executing the command.

Conclusion

Info

With these steps, you should have successfully migrated your Openbravo data to Etendo either on a Linux system or on a Windows system. If you encounter any problems during the process, please reach out to the Etendo support team for assistance.
