How to move published albums between lightroom catalogs

I work with photos on several computers. both at home and when travelling. This has created chaos. Can anyone give me good advice on how to move albums between catalogs in lightroom.

I worked with https://myvo.is on a laptop.

I worked with m70 - Myvo ehf under myvo.is. Did not have access to the home computer that contains https://dagbok.kristinn.no

Now I want to transfer M70 from Myvo.is to dagbok.kristins.no and continue working on ligtroom kaltog on my home computer

Can someone give me some good advice

you can move Publisher collections from one Lightroom catalog to another using the Lightroom Voyager plug-in

This plugin hasn’t been updated for the last couple of years though, but it’s still the only plugin I know of that can do what you need.
