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

Tao is investigating but hasn't been able to recreate.<br>
<br>
While triaging all the issues I updated the ones for migration with a 'migration'
tag and updated the replication ones with a 'replication' tag.<br>
<br>
If you have any questions/concerns about this, please let me know.
Otherwise we will work towards cleaning these up.<br>
<br>
Thanks!<br>
Jay<br>
