Check if you have setup unique IDs for ODI repositories (master/work).
These IDs needs to be unique in all ODI environments.
Use Smart export/import to migrate ODI artefacts.
Please see few more notes:
How To Move The ODI Repository To a New RDBMS Instance (Doc ID 423585.1)
Thanks Adrian. As pre-requisite I have updated both repositories to be same in new environment. Can you share the sequence of artifacts for the migration (like Physical architecture with required technologies, logical architecture, context etc., first and then work repository artifacts etc.,)?
