New domain data migration
Having been discussing virtualisation projects with a number of suppliers recently another idea has got into my head that might be easier... rebuild from scratch rather than migrating the old domain onto a virtual infrastructure.
We've currently got two networks and I'm weighing up whether the ease of management of a unified teaching \ admin network outweighs the security of separation by wire.
If we went down the new domain route the main issue is how to seamlessly move department \ home drives over as well as Exchange.
Part of the issue would be that the current group names \ setup is really out of date now and would be an ideal opportunity to rebuild so a rough idea in my head would be something like...
- backup \ restore the shared drives to new network
- create new security groups as appropriate
- replace security permissions on restored folders to propagate all the way down with new groupings
- ownership... the owner on the files wouldn't match up to anything on a new domain so would it just be better to replace all with administrators group on the file server?
User folders would be a real pain as they're set up as one share per user at the moment (legacy setup not me!) so would have to somehow change that to the standard single share \ subfolder per user standard method... via script somehow I guess?
Exchange... could do the trick we did when migrating from 2003 to a fresh 2007 install and run an export command to send each mailbox to an archive in firstname.surname.pst format, which it then imports back in providing there's a user with the same name in the new AD it can match up to.
There's also an Exchange cross forest migration tool I've spotted but not sure how much work it would need for the old and new domains to be able to talk to each other?
The users could be done with an AD migration tool but then again it could well just be easier to get a list of current staff from personnel and recreate the accounts from CSV or equivalent. That way no legacy info from the old AD would get carried over.
Would be interested to hear from anyone who's gone down the rebuild route as now is probably our best chance to do it with new, virtual servers and shiny new OS :cool:
