SBS2003 to SBS2011 - How reliable is migration tool?

Posted on 2011-10-23

Hi all,

Im planning on upgrading our SBS 2003 machine with 5 users to SBS 2011.

2011 has the new migration tool. How reliable is this? Last time I tried to do a migration to 2008 (different network) it was very difficult and we ended up rebuilding the network from scratch.

so, How reliable is the SBS2011 migration tool when moving from SBS 2003.

Thanks for your input

    The Migration TOOL does little more than check a few health settings and confirm certain software is installed to allow the migration to occur.  

    I'm in the middle of one now and I did one two weeks ago.  The only problem - which I've seen multiple times now - is that AD replication tends to choke until/unless you hit retry.

    If you want a SUCCESSFUL migration, you need to make sure your existing network is healthy and then follow the Docs (Jeff's method is excellent and if you want to be really safe, I strongly recommend you consider it and spending the money necessary to obtain it).

    1) Can I run the Migration Tool on the SBS 2003 machine now to check its 'health'? I dont have 2011 software or new hardware yet, still researching.

    Just reading about Jeff's method now...

    2) It seems you need a third machine for a temporary DC? Without access to spare hardware is this 100% required?

    Thankyou both.

    Yep... but it can be almost anything... a VM on a notebook works fine.  After all, it is a temp DC, and Server 2003 at that.
