Hi,
I am trying to Upgrade BC15 to BC 20. https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/upgrade/upgrade-unmodified-application-to-v20
When executing Get-NAVAppInfo I am getting more than 30 Extensions. In Business Central Extension Management I can see only 3 Installed. I tried to uninstall and unpublish all those extensions with no luck. (Before, I had more that I manage to delete them).
When I am trying to uninstall (Uninstall-NAVApp) each of the 3 installed extensions I am getting error: An item with the same key has already been added.
When i am trying to unpublish (Unpublish-NAVApp) an extension I am getting error: The Extension cannot be unpublished because it is in use by the following tenants
Please help me identify the issue as I am not able to proceed with the upgrade
