problem with transfer export import reference data

[doctor_uv]

I am trying to move my transformation and codegen templates from one project file to another. However, I get a unique index error when I try to do that with my modified version for the second time and it does not work.

Is this a bug maybe? For the model XMI I can select to ignore GUIDs of the elements - for the reference data this is missing..... :-(

Do I have to manually modify the XML file during the transfer?? Is there a way to delete unused templates? Do I have to get my DBA shirt out and do it in the database?
Question over questions - I seem to have found an area where the workflow is not completely sound....

Any help is greatly appreciated as the current solutions seem very tedious.

so the DBA approach works on an oracle based model .....

I can go to the database and

[glb]delete from t_template where templateType like '%_Template';[/glb]
after that the import of the modified templates from the other EA model works!

seems very awkward though!
and won't help if you are using EAP files ?

Why shouldn't that work with EAP files (just curious)?

Btw. %_template does remove every user defined template, doesn't it?
