OpenVPMS doesn't directly support data migration from other veterinary practice systems.

It does however provide a plugin for Pentaho Data Integration (PDI) that can be used to get data into OpenVPMS.

The plugin works with PDI 9. This can be obtained from here.

Extract this zip file to a directory. This will be referred to as <PDI_HOME>.

To install the OpenVPMSLoader plugin:

1. Remove any existing openvpms-pentaho-plugin directory from <PDI_HOME>/plugin
2. Extract <OPENVPMS_HOME>/import/plugin/openvpms-pentaho-plugin.zip to     <PDI_HOME>/plugins
   This should automatically create a subdirectory under plugins named openvpms-pentaho-plugin
3. Copy the MySQL JDBC connector from <OPENVPMS_HOME>/lib to <PDI_HOME>lib
