DISM commands missing (error 87)

Question

After trying to use DISM /online /Get-TargetEditions on a Windows server 2012 essentials installation in order to change the version to 2012 standard and much to my surprise, I received an error 87 stating that the get-TargetEditions is unknown command.

Has this occured to anyone and if so is there a way around it?

Thanks in advance!

Answer 1

You could try a repair install but the much simpler / safer method may be to stand up the new Standard for replacement.

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.
