Situation is currently 2 domains 123.com & 456.com, seperate forests with exchange 2003 orgs merging into 1 doing away with 456.com
My plan was to export mailboxes(EXMERGE/exh mig wiz), export user groups etc (ADMT), 456.com DC's removed and added to 123.com,DNS/replcation set up + other config for new DC's etc, 456.com Exchange servers re-imaged with a pre configured Exchange installation correct for 123.com, mailboxes migrated back in. LDIFDE used to import some old mailbox attribs to old users of 456.com so still addressable (as ADMT doesn't migrate the exchange info interforest)
I have tried and tested several methods in a test environment all steps are feasible as far as I can see however I have stumbled a little with Exchange mailbox migration largly due to time and fincancial constraints. I have no hardware on which to install exchange and migrate mailboxes over slowly and have a 16 hour window to carry out the migration. Using exmerge or exchange migration wizard to move mailboxs off the servers take around 20 hours as there is lots of data!
Can anyone offer me any advice on this approach? This is the first time I have tackled this type of project and I think I may be on the wrong track a little. Is there any way to complete this leaving the mailstores in tact??
