I think SBS has done a disservice in making active directory deployments easy. Then when one needs to migrate one doesn’t realize that this isn’t a trivial thing. For several years…ever since SBS can no longer to an inplace upgrade people have been asking for an easier migration. Something simple. But we’re overlooking the obvious. We grow complexity over time. We add printers and shares and databases and line of business applications and it’s not simple anymore.
If there is one thing and one thing only that I will tell you to do before migrating is run the www.sbsbpa.com as that will for sure catch the number one gotcha — journalwrap errors.
But people want simple printer migrations and the problem points out the age of printers and the various printer driver issues.
People want an easy exchange migration and the Exchange team has changed the database format between 2003, 2007, and now 2010.
When we start moving things, making the decisions to move to the cloud there were be issues as well.
The best thing you can do is understand that making something simple never is, and only if you have inflexibility for small businesses will a “Simple” migration occur.
