That is almost impossible. Upgrades are parallel installs where you migrate the data over. 

What exactly makes you say v2019 is reading the same data as v2022?

Some workstation files are shared, like your launcher favorites. Those settings are stored in your local My Documents folder, not in the server path.

For Standard / Advanced: SOTAMAS90 queries will be pointed at the data for the most recent Sage 100 login on that workstation.

For a Premium upgrade, if whoever did the upgrade moved the upgraded SQL databases back to the original instance, they should have disabled absolutely everything to do with v2019 pointing at that same SQL instance.

And yet here I am.

Data migrated. V2022 seems to be just fine.

All new entries in 2020 also show in 2019.

It looks like 2022 but the version on About Sage says 2019.

Stop using v2019 entirely, and contact whoever did the upgrade, for clarification of how they processed the upgrade.  What you describe should not be happening.

Hmmm... Update.  It was the Favorites that made me think v2019 was reading the v2022 data so I looked at my most recent SO Invoices.  I had forgotten I processed a few May invoices before the migration... there isn't any duplication.  The Payroll I processed today is NOT in v2019.

So I am probably good at this point.  I just don't know if I can retrieve my Favorites from the 2019 install.  If not I'll rebuild from scratch.

Do you mean the Classic launcher's My Tasks?  There's a utility to import those as Favorites.

Not My Tasks.  Favorites.  I use them as checklists for Month End closings for each module and Quarterly processing for Payroll.

I recreated the one for Payroll Processing in v2022 today - it's simple.
It showed up in v2019 when I looked for the other Favorites I had set up.

So apparently at least the Favorites is in a common space for both installations and they didn't come over with the migration.  Maybe there is still a file in v2019 I could copy into the same location for v2022.  That would be helpful but it's not a huge job to rebuild the lists... it's just remembering what they were.

The new Favorites are stored in the local Documents folder, for your Windows profile.  If you were using the new Launcher in the previous version, your previous Favorites should be there already.

Prior to the update in the Sage Launcher, there was no "Favorites" feature... it was called My Tasks (using the Classic launcher) which were stored in a different place.
