Moving to a new computer - cannot find "other catalog files" to transfer

[jenshauge]

Lightroom Version Number

5.7.1

Operating System

1. iOS

We have Lightroom 4 on an old Mac and Lightroom 5 on another oldie. Having now bought new (silicon) Macs, we will transfer Lightroom files and update program. It is a big jump to go from 2013 to 2021.
In the pdf "Lightroom. Moving to a new computer" Chapter 5, on page 11 we are advised to do backup of certain files and referred to the path to find them (location). However, some of these files do not seem to exist in LR 4 or 5 on our Macs:
The other catalog files": *lrcat-shm, *lrcat-wal, *Helper.lrdata and *Sync.lrdata.
Can anyone explain this? Does it have to do with our versions being old? Does it matter?
Would appreciate advice, we are a bit nervous.

They were introduced in Lightroom 6, so don't worry about them not existing.

Welcome to the Forums and all the best with the migration, there's a lot improved from the versions you were running to the current Lightroom Classic!

Thank you! What a relief …
