You can optimize databases for merging your contents.
Prerequisite
You have the Database export privilege for both the source and the target database.
Procedure
Ensure that the Name attribute of all groups is specified in the source database in the database language you want to use to run the merge. The database language is used as the conflict recognition language by default.
Reduce the number of objects that have the same name in this language.
Remove object definitions that have no occurrences in models from the source database, so that the merge is only performed for essential items (reorganization). Please note that object definitions without occurrences that are not to be deleted may exist in models because they are to be reused at a later time. In this case, do not reorganize but remove the object definitions without occurrences manually.
Ensure that the models and object definitions you want to transfer to the target database are in the proper groups and that you have Read access privileges for these groups.
Ensure that you use a method filter in the source database that includes all the items you need.
Log in to the target database with the Entire method method filter.
Ensure that the Name attribute of all groups is specified in the target database in the database language you want to use to run the merge.
Reduce the number of objects that have the same name in this language.
Ensure that the models and object definitions you want to merge are in the correct groups and that you have Write access privilege for the groups.
Create a backup copy of the target database because a merge cannot be undone.
You have prepared the databases for a merge.
