Hi..... i upgraded from Lightroom 2015.6.1 to Lightroom Classic 9.2.1 a few months ago. I still have both versions on my Windows desktop and only using the new one. but i seem to have 2 catalogs now as the new version i use has Lightroom Catalog 2 on the top of the program when it is opened.
Can i safely uninstall the old version without it affecting the new version or catalog? I am getting a new desktop within a week probably so would i need to worry about the old version of lightroom and just move the new catalog over to the new computer?
i just downloaded the free e-book on how to move to a new computer.

I would simply zip up the “.lrcat” file representing the old version and move it to your backups folder. When you upgraded to v9. Lightroom Classic copied the data out of your old catalog and created a replacement catalog with the “-2” added to the catalog name. It is compatible with the v9 catalog structure. You should also update to LrC v10 which will repeat the upgrade process on your current master catalog and add a “-10” to the catalog name.
