All,

In discussion with Mike Perez earlier this week the following bugs were 
highlighted in Volume Migration and Volume Replication.  IBM is focusing 
on investigating and resolving these bugs.

I will be putting out updates as we progress towards resolution of these 
issues.

While triaging all the issues I updated the ones for migration with a 
'migration' tag and updated the replication ones with a 'replication' tag.

If you have any questions/concerns about this, please let me know. 
Otherwise we will work towards cleaning these up.

Thanks!
Jay
