Problem with OST file

J

Jens Tolkmitt

Hi all,

I have a big problem migrating the Offline store in Outlook. The Situation:

~3.000 Offline User in one Exchange organizations, Exchange 5.5 and Outlook
97. The Offline store Volume is ~30 GB. Now I must move the Server from this
organization into another organization (because I have to consolidate this
two orgs, later migrate all to Exchange 2003). Whole number of users in both
orgs: ~40.000.

When I move the server to the new org, then the Offline store is wrong and
the user must replicate the whole content again (after deleting the store on
the client e.g.). The problem is: I have only 4x 2 MBit connections for
that. And when I move the whole server, all user will try this in a very
short timeframe. That is not acceptable. Good is that I don't must change
the messaging profile by moving the server (because the server name will be
the same), the problem to press the "check name" button in the profile
configuration I fixed with delete of five registry keys in
H_Key_Current_User.

Question: Is there any way to patch the Offline store so that this will also
work after moving the server?

The other way is to move the user step by step in a client migration
process. But this will stay more then four month an I will have a lot of
replication trouble (Notes, MEMO... all stuff is included in the GAL). The
manually effort is very big then.

Regards

Jens Tolkmitt
