Upgrade server from 2008r2 to 2012r2

Hello, We need to upgraded old hardware which has server 2008 r2 dc running its a single dc environment so I thought it’s better to upgrade to server 2012 r2 along with hardware upgrade, can someone please help how can I initiate this upgrade process smoothly to have all our existing domain controller information and get rid off of server2008 r2.
Thanks

Since you are introducing new hardware this is a very straight forward project.

  1. Rack and stack your new hardware.
  2. Install the OS of choice (2012 R2)
  3. Join the machine as a member server to your domain.
  4. Add the ADDS role and promote this to a DC.  
  5. Confirm replication
  6. Move FSMO roles
  7. Decommission old DC

do not upgrade existing hardware since you have only one dc, if it fails you will lose functional ad server and then u need to start another project of recovery

Just quick question poped up in my mind because it's very small business about 20 users so what if want to move DC to office 365 instead of on prem hardware what would be the process then any idea?

I have not done this yet. I know there are a plethora of how to on the internet. I would recommend posting a follow up question as this is a completely different process.

The question here is, do u really need dc at all only for 20 users?

U can simply use cloud only accounts for o365 email access

Still u wanted, you should keep dc onprem only
To put dc in cloud, u need vpn tunnel which joins on premise network to azure (site to site) and then install dc in azure , now connect your clients to dc in azure
