I've newly set up an exch 2007 server and intend to use it as a SCR targe server for another Exch 2007 server which is already in production. I will use update-storagegroupcopy to do the seeding but I am afraid it will seriously affect the performance of the SCR source Exch 2007 server during seeding. Will it take a long time for the seeding process to finish (the edb file is 50GB and both source and target are in the same office) and do I have a way to stop the process if it ready does seriously affect the performance of the SCR source server while seeding? Thanks in advance.
