domain&forset function level 2008r2 raise or and add a DC server 2019

[chazzy2501]

I have server 2019 members just fine the domain controllers x3 are 2012r2 the forest and domain are functional 2008r2. I think I can just go for 2019 in place upgrade but people are mumbling about SMB1.0 needing to be enabled. Do I raise the functional level to 2012r2 (can i)

 

just to tickle some memories for those who did this 5 years ago

 

Once I get them to 2019 I can raise again to functional 2016?

 

cheers

I've always been suggested to spin up a new DC, leave it for a day, turn off the old one

Then see if anything breaks.

 

Doesn't 2008r2 use FRS? Wouldn't that need to be migrated, then move into the new DCs?

SMB v1.0 will be disabled when you go through that process, so check it’s not needed (it stopped some of our old NASs working back in the day, so I binned them).

This is the way

Thanks everyone, I got stopped by the new DC I was trying to add complaining about FRS being in use. doing a dfrs migration now!

 

could have been messy if I tried an upgrade..
