Server Migrations
Sunday, January 20th, 2008Before you launch on your next server migration product, take one hour and visit these websites:
and this one about Exchange migrations.
Read the sample docs a few times. This is a radical departure from standard migration methodologies, and it took me about two days to understand what these sites are talking about.
The documentation on “swing migrations” is clear enough, although the concept is new to me, and took several readings to fully grok what’s going on. Essentially, when migrating via the “swing” method, you will end up with your new hardware and all your software (Active Directory, User & Computer Accounts, File/Print Shares, permissions, Exchange and SQL) and the server and resource names will be the same. This is in stark contrast to other migrations, where the DC name changes, and ultimately the UNC paths for file/printer shares break, Exchange mailboxes must be exported and imported (Exmerged) and SQL connection strings and ODBC drivers will all need to be updated.
The method leverages the well-known method of force-removing a domain controller from Active Directory. If you’ve never the opportunity to enjoy that fun, please call me and I’ll be happy to do it for you. Trust me, your time plus the lost years on your life plus the $245 call to Microsoft are far more expensive than my fee.
In any case, if you are going to do a migration, GET THIS DOCUMENTATION kit. Then practice, Practice, PRACTICE these methods on your own test servers! Use VMWare (it’s free now) or Virtual PC if you have to, but make sure you PRACTICE these techniques before you touch a production environment.
Along the lines of migrations, I have yet to test a new product from www.platespin.com which allegedly claims to be the solution for server migrations. Beyond just P2V (physical to virtual) migration capability, which is now free from VMWare and Microsoft, it advertises V2P (virtual to physical) and P2P - that’s NOT peer-to-peer but rather physical-to-physical.
That’s right. Old hardware to new hardware - no reinstalls, no reconfigurations, no long restores of data from backup. They even claim you can do the move while the old server is still online.
$200 per migration - and at first glance, probably the best money you’ll ever spend.
