Migrating Exchange 2003 organization to new 2010 organization

Experts,

We recently acquired a company, who is currently running Microsoft Exchange 2003.

We have an existing Exchange 2010 SP! infrastructure.

We are planning to migrate all AD user accounts using ADMT, and then mail enabling these users on our existing infrastructure.

We have the requirement to migrate users' existing mailboxes to their new mailbox inside of our Exchange organization. What tool can I use to bulk export/import, considering the version differences in exchange?

Also they use a complex public folder infrastructure, that we need to migrate as well, is there any tool/process to complete this as well?

I do realize there are third party companies charging money for these types of migration tools but i'm not looking to spend a boat load of money on toolsets..

Any help would be greatly appreciated!

Any chance of getting an Exchange 2010 server in there, at least temporarily?
If so you could do a cross forest migration, which is very easy with Exchange 2010 and well documented on TechNet.

Otherwise it is a PST migration for the mailboxes. Public folders will probably have to be exported by hand to PST files and then moved across.

Was the above a typo for Exchange 2010 SP1? If so you really need to upgrade. SP1 hasn't been in support for some time - only SP3 is a supported version.

simon, no it was not a typo we are running SP1, have a project tin the works to upgrade to 2013 now, but it will not be ready in time for this integration project.

I don't think installing a 2010 server in the existing organization, and then doing a cross forest migration is an option, however I don't want to rule it out..

I was thinking of exporting the mailboxes with EXmerge, but have no experience with it.

And is it possible to export the root public folder which exports everything to PST? will it maintain security setup?

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

If you want to upgrade to Exchange 2013, then you will have to upgrade Exchange 2010 past SP1. Therefore I would schedule the downtime as soon as possible and upgrade.

You cannot maintain the public folder security structure if you use the PST file method. Everything will be lost. For public folders I am pretty sure you cannot go cross forest, it is only mailboxes that can go cross forest, so you are probably looking at third party software to do the move if there is a complex structure in place.

Exmerge is basically a PST export, there isn't really much to get "experience" with, other than it is slow. You will also have problems with replaying to old emails, calendar entries etc, which is due to the missing/difference X.500 addresses.

This blog from the SBS product team explains the problem:
