Data model cleanup

Dear all

A big client of ours is using Alfresco in an archiving use case. They are putting in documents and custom metadata for over 5 years now, and have been extending the model on a regular basis. The repository contains about 8 million documents. The document model has a lot of unused fields and also duplicated properties with a slightly different name. Now we want to cleanup the document models. This is what I have in mind right now:

1) Design the new document models
2) Setup a new Alfresco with the new models
3) Do a migration from the old Alfresco to the new one, mapping the old properties to the new ones. (We have our own migration product, move2alf, supporting CMIS as a source.

Since this is a big Alfresco, this process will not be easy. Does anyone have experience in doing something similar, or advice to take a different approach?

kind regards
