I created the missing table from CollectionComputers and now have this error.
I'll keep trying to supply missing pieces, but I am not putting a lot of faith in the end result. Help!!!!!
Assuming the jump from 19.0.40.0 to Inventory_19.3.48.0 was too much for the upgrade to handle, I backed it all out and started over.
Uninstalled, installed the version we had working, Inventory_19.0.40.0, 4/28/2020, 4:56 PM EDT, success.
Installed the next available version with success, Inventory_19.1.96.0, 8/11/2020, 10:42 AM EDT, success.
Trying to get to the next version, Inventory_19.2.137.0, 11/5/2020, 9:47 AM EST, this fails once again with the missing table error:
-no such table main.Old_CollectionComputers
It is desired to continue upgrading to a more recent version; we have several to install.
