You are asking an impossible question. There is that much data and information being transferred you never can tell nothing has been missed. It is more easy to find something that has been missed.
The questions I can see are:
- your new system should work according to requiements. That is a technical en functional test as separate approach
- Your data should be migrated to new locations. It should be verified within an isolated environment (no external connections).
This is a similar question as can you backup/restore your system. When you cannot answer and give a proof for that why would you do an audit on that.
- With new versions the real implementation changes. It is a new version.
What you can do after all functionality is verified is checking/verifying visual at some random chosen metacontent whether all is there with the metadatabrowsers.
There is a product metadcoda that is helpful on the generic metadata content not the dedicated solutions ones.
Building your own extraction programs is possible but will need a lot of work.
