I am in the process of configuring SCR in a my environment. We have a single copy cluster configured in production (active/passive ) and a passive node of a cluster without the mailbox role installed in the DR site (yes, these servers are physically in different locations).
Obviously all my exchange servers have SP1 installed but in addition have installed update rollup 2 on them. SCR has been configured and replication is working flawlessly! currently no active users are on the servers so we are testing different scenarios but we do have test accounts. When I run the SETUP /RECOVERCMS to activate the DR server, I am getting the following error:
"You must perform disaster recovery using the same version of Exchange as the last installed version. The current installed version is ‘8.1.278.2’; the last version installed is '8.1.240.6"
I cannot get the setup to run at all! Has anyone seen this error before? Any ideas would be helpful.

Yes, we have seen such issues earlier - there are only two solutions for this.
1) Search for the value in the registry value at location v8.0 for 8.1.240.6 and replace that with 8.1.278.2. Once thats done try the /recovercms - see if it works - else go to ADSIEDIT and check the properties of "your E2k7 box" - the attribute is server version - replace 8.1.240.6 with 8.1.278.2 {i dont rem but it was something like 8.1 (30240.6) and that needs to be replaced with (30278.2) } -excuse me for gettting some data wrong - since i dont have my lab access right now unable to tell u exactly.
2) flatten down everything and that should work all the time (too nasty a solution but thats what PSS Team always states)
This is a known issue. No need for extensive hacks or registry or AD changes. Simply remove the UR from the system, run /recoverCMS and after the CMS is back, re-install the UR.
Hope this helps.

Thanks for the input guys! I have overcome that obstacle now and have been able to clear the CMS on the production environment. Now I am faced with another issue. Currently everything is running out of the DR site and am reconfiguring the production environment so that I can restore everything to the way it was (i.e.: exchange is running out of the production environment)
"If the storage used by the original failover cluster was unaffected by the failure of SITEA and if the original databases and their transaction logs for the three storage groups still exist on NODEA, it may be possible to use them for continuous replication purposes without having to perform a full reseed for each storage group on NODEA"
GREAT!!! ummm How???
The databases in the environment are still intact and range in size but are mostly over 80GB. I have tried to update the storage group copy but it keeps asking me to delete my transaction logs and database files. Is there no way of having the transaction logs deleted while leaving the database files and having only the logs replicated over from the DR site since it is currently the active site??
Any help is greatly appreciated!
Thanks
