I have read all the SCR articles however the one thing I did not come across on the requirements was can I have on the Source Server: E2K7 SP2 Enterprise edition but on the Target Server: E2K7 SP2 Standard edition? many thanks

Hiya, If it's a CCR or SCR cluster as the source (which both req. Ent) you need Exchange 2007 Enterprise licensing, otherwise standard is fine. SteveSteve Goodman Check out my Blog for more Exchange info or find me on Twitter
