Hi Hemalatha S.
So, for a 'short period of time' you'll then have 2 mdb databases running?
And then I understand your question about 'synchronizing' ca_contact data.
When you have SDM and SC (and PAM) integrated, then it will not work, having two separate mdb databases.
Not even for a 'small' period.
As far as I can see, the approach then would be:
1. Use the current integrated mssql/mdb database environment
2. Upgrade SDM
3. Upgrade SC
4. Upgrade the mssql environment
Please advise. Thanks and kind regards, Louis.
