What is the need of RAS Report during AD Upgrade from Ws 2016 to 2019 and how do we extract this?

Question

Hi Everyone,

I want to start with the AD Modernization Project to upgrade DCs from 2016 to 2019 and I would like to understand the need for RAS Reports, how to extract them, and their importance.

Thanks.

Not sure what report you're asking about.

The two prerequisites to introducing the first 2019 or 2022 domain controller are that domain functional level needs to be 2008 or higher and older sysvol FRS replication needs to have been migrated to DFSR

I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting any operations. Then stand up the new 2019 or 2022, 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.
