Hi,
I would suggest using the APIC Toolkit to interrogate the available content in v5 and run the equivalent commands against the v10 system and compare the results,
If assistance is required for such activities I suggest contacting your local IBM Expert Labs Sales team to arrange input from local IBM Expert Labs consultants.
