Exchange Migration Store Question

Hello,

I've been testing a migration to move email from an Exchange 2007 to Exchange 2010 server. It's about 60 users or so and am going to just export and import as it's a brand new domain.

I've tested it and mapped X500 addresses so there are no bounces. As well as turn on circular logging to cut down on transaction logs during this phase. What I am wondering is should I expect an information store of around the same size on the new server from the old?

It is around 100 GB. Not sure if others have experience with this as I've not had to do this before.

What i meant was the SIS would be broken if any on the old database while you export the data from users mailbox to PST ..... so once you have the data in PST you can check with the collective size and thats what is the total size and if you have Exchange 2010 SSTD you can have 5 Database ....
