Schema Upgrading RRS feed

  • Question

  • Hi. I recently upgraded my servers (DCs were at 2012R2 and 2019). I upgraded the schema from 2003 (a nightmare left for me by the previous admin) to 2012R2. I have since decommissioned the 2012R2 DCs and have two 2019 DCs. The GUI schema tools show the Domain and Forest schema as 2012R2, upgrade-able to 2016. I know that that is as far as the GUI will go, and I would like to tell it to update the schema, but.... when I checked using CLI/PS, the schema reports back as 88, in other words...2019.

    Would it be harmful to tell the GUI to change to 2016? Will this affect the CLI/PS or the actual schema level? I know it is possible to lower the schema level. Would changing it via the GUI force the actual schema version to revert to 2016, or be harmful in any way?

    I'd appreciate any insight.

    Thanks.

  • Might also check;

    Get-ADDomain
    Get-ADForest

    then check the resulting ForestModeDomainMode

  • Please re-read my post. The issue is not determining what I have...I know what I have. I am simply asking if there'd be an issue in doing the schema update via the GUI. That being said....running the above commands both showed the forest/domain as 2012R2. But then why would the other Powershell checks provide me with an 88?

    Should not be an issue.
