Re: tgsv50 and AIX patch info


Our schedule call for completion of the upgrades by end of March.  I will be 
to slip this, but want to move forward as quickly as is reasonable.  The 
though is our problem, not yours.  As long as there is movement towards 
of the problem we will deal with the schedule internally.  We do indeed have
operational issues due to running without a backup.  If you do not expect a
resolution before April 2, we will begin efforts to roll-back tgsv50 so as to 
backup capability in place.

Frances Yang will contact you today to discuss details of the AIX test system.  
expect that at the latest, we can have that system online and ready for your
access by the start of next week.
