Windows Server migration

Question

I just started working in a company and we have Windows Server 2003, I would like to know if we could migrate it to a more recent update, therefore I would like to know how I know what type of license (to know if you could do it) I have and also a tutorial (a link or another similar thread that they have passed) thanks guys.

Answer 1

if it is possible to migrate with the configuration we have from 2003 to 2016 for example.

Assuming you're asking about a domain controller?

The prerequisite before introducing the first 2016 domain controller: domain functional level needs to be 2003 or higher

I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting any operations. Then stand up the new 2016, patch it fully, license it, join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to again verify health, when all is good you can decommission / demote old one.

Also at some point after I'd recommend migrating sysvol replication from older FRS technology to DFSR

Answer 2

Windows Server 2003 is too old and end of support.
But please understand that changing the OS of a DC or other roles server is not an easy thing, it is related to many aspects and can influence many people’s work.
Since you just start working in your company, I suggest to discuss with your IT teams and system admins for an idea.
The latest server OS is Windows Sever 2019, which has many differences with server 2003, you could try the Evaluation version for trial.
