Hi Hiranya,

I think this sounds like a reasonable approach. The recently written 
UpgradeTrajectoryTest does something similar: it compares the metadata 
in Before and After databases. You may get some implementation ideas if 
you glance at that test. Two tricky bits about comparing metadata are 1) 
you need to remap UUIDs, 2) timestamp columns are unstable. 
UpgradeTrajectoryTest.normalizeRow() may help you sort through the 
expected differences.

Hope this helps,
