One of the most frequent asked question is how to locate resources if Exchange 2010 migration is on the way. If you do not have previous experience and wish to go for migration you may want to check fallowing resources before and during migration.In general migration process is much simpler if I have to compare the previous migration scenarios, I need to admit going from E03 to E210 or E07 to E210 is fairly simple. The question is what hardware to purchase? your scenario might be or will be different, if you are purchasing new HW , talk to Vendor to see their best practice papers they normally do have established baseline which may make your job easy.
The future of Exchange product line seems to be “Online” hosted services, only reason I say this is the key factor “Cost”. MS seems to be very push when it comes to MS hosted platform, I have seen MB prices goes down to couple bucks with adequate & reasonable price. After all it could make more sense to go to Cloud. This of course is not cast into stone as I said every one will have different scenario needs etc.
Whatever your scenario, below links may help you going forward and good luck on your migration.
