In order to upgrade a {{UBIK}} Environment from version 3.7 to version 4, it is necessary to create a new database and to transfer the data from the old database to the new one. Here's how.
{{Hint|
'''Custom code compilation errors: Implicitly abstract classes'''
Custom code assembly improvements have led to the effect that obsolete "legacy" MetaClasses originating from pre-version-4 databases get in the way of building the customizing and must be either deleted or marked as abstract (setting the ClassType property to 50).
Any valid custom classes that use abstract custom code must also be marked as such via their ClassType.
'''Obsolete classes''':
* IMAGE_MANAGER
* SYSTEM_IMAGE
* DISPLAY_DATA_APPLICATION
* OSIPI_SERVER (if you're not using the OSIPI Plugin)
* OSIPI_DATA_POINT (if you're not using the OSIPI Plugin)
* SYMBOL
'''Namespaces with obsolete classes''':
* System.DataExchange
* System.DataExchange.Relation }}
