Copying Documents Between PeopleTools 8.51 Databases

If you copy a document schema from a later release to a PeopleTools 8.51 database, schema validation may fail. Delete the schema before you copy the document to the PeopleTools 8.51 database; the system automatically rebuilds document schema when you save the document or deploy it.

There are no restrictions for copying documents and associated document schema from a PeopleTools 8.51 database to a later release
