Upgrading old lightroom 4 catalog to Lightroom Classic

[mmsf_ca]

I've got an old lightroom 4, which has some catalogs I haven't touched in years.

At this point, I need to upgrade them, and I tried finding a Mac OS version of lightroom 6 to make the jump.

Has anyone had this issue in the last year or two? I don't want to lose the catalogs if possible.

The upgrade should have no issues, and your original catalog will be kept untouched. So, nothing to lose. 

As for going to LR6, you have a perpetual license? 

For where to download old versions of Adobe installers:

Thanks for the link. However, when i download the DMG, i get this:

Any idea why? 
I'm not able to install it for some reason.
- I'm on MAC OS Monterey 12.6.2

Because part of the LR6 installer is 32-bit code, whereas Monterey (and Big Sur and Ventura) are all 64-bit only.

Thanks for that. Can you think of any workarounds?
Sorry, total newbie to this.

LR6 should run as a 64-bit application under Monterey and maybe Ventura (I never tried that) but installing it is the issue; you must boot into an OS that can support the 32-bit installer (the last being Mojave). That's a big problem for M1's because Monterey, Big Sur, Catalina and M1 Macs do not run 32-bit and can't boot into Mojave. 
IF your new Mac isn't an M1 (Apple Silicon), you are OK but if it is, you're SOL.
