Move FSMO roles...

Hi Experts,

I have an very old DC with FSMO roles installed.
This is an old WIN2008 server, no R2.
Can I move the roles from WIN2008 to an WIN2012R2 server ?
And please can you give me some hints and links ?

Transferring FSMO roles really hasn't changed much in the last 15 years. You can move them between versions without issue, and any reliable tutorial (or TechNet article, which i recommend So you avoid following bad random internet advice...vetted sources and all that) )written in the last decade is about all the guidance most people would need. The process is trivial. But as always, a backup before *any* change is a best practice.

That has guides on FSMO transfers at the bottom

  1. Transfer the Schema Master
  2. Transfer the Domain Naming Master
  3. Transfer the Domain-Level Operations Master Roles
  4. View the Current Operations Master Role Holders

Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

It's advisable not to, but as long as the move is clean there isn't any downtime.... However.... If it goes wrong, you'll need to seize the roles, that could cause issues.

I'd recommend an out of hours move to be honest.

does my users recognice the change ?
AlexProject Systems EngineerCommented:
No they don't, unless it goes wrong, or they change their password as you're making the move... It's really best to do it OOH

Yeah, moving FSMO roles is nearly always straightforward.

When moving PDC ensure that you configure the Time settings to NTP and other to NT5DS.

Ensure that you have no replication errors before attempting (note the *)
