2 Versions of Lightroom on my desktop

[#1]

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 10 desktop but only using the new one. 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?

Also 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?

Lightroom 2015.6.1  ie. Lightroom v6 from 2015- way old!

Yes.  You do have backups of your current working catalog Lightroom Catalog-2  don't you!

Also I am getting a new desktop within a week probably so would i need to worry about the old version of lightroom

No.

and just move the new catalog over to the new computer?

Yes. But there is some more things to consider - eg. re-installing Lr-Classic (now at v10 ) and Presets, etc.
