Re: Migrating to 2003 AD today – quick question
Please make the schema upgrade on the schema master server.
To avoid overhead on this server, you can connect it to seperate LAN/VLAN.
You can do the same thing with domain upgrae by moving the infra. FSMO to seperate LAN, upgrade the domain version on it and then move it to the LAN.
After a while (until replications will be finish) you can upgrade the operating system version to the latest one.
Its recommanded to test the upgrade in a lab first.
