Subject Re: LCS and counters
Date Tue, 05 Mar 2013 16:50:06 GMT
Well no one says my assertion is false, so it is probably true.

Going further, what would be the steps to migrate from STC to LCS ? Is
there any precautions to take doing it using C*1.1.6 (like removing commit
logs since drain is broken) ?

Any insight or link on this procedure would be appreciated.
