Based on experience (as mentioned), this would be risky.


The page suggests on can have two versions in parallel (I am interested)

   "If you have upgraded from SDL Trados Studio 2017 and would like to continue using this version, please refer to this Wiki article

which is obsolete.

I have no idea why you think this will be risky!  I have already told you that running in parallel is possible.

The link you refer to is a very old one... try this:  04.6 Installing and activating Trados 2024 and Trados 2022 side by side (upgrades only) 

I found it by following your instructions to search for it!

But compatibility is not guaranteed.

This will remove the 2021 and replace it with 2022 since you upgraded and you didn't purchase an additional licence.

No, it's a licence for 2022 only.  It might support the ability to run 2021 without a licence on the same machine only as we often do allow this.

I'm in the middle of a large project.

This has nothing to do with running them in parallel.  Both my quotes are accurate.

But I take your point.  It is never a smart idea to upgrade in the middle of a project.  Even if you do upgrade and have both versions running on your machine I would suggest you always finish out existing projects in the old version and only start new ones in the new one.  Most of the time you won't have any problems, but if the version you are upgrading from is using filetypes that happen to have been completely updated, or replaced even, then you could indeed have problems.

I'd be happy to have 2 functional versions *installed*, and running only one at a given moment.
It's still unclear to me whether the licensing policy allows that.
Does it?


As for ongoing project: certainly it is better to complete it first.
I don't use many filetypes - mostly docx and xlsx (sometimes pdf as input, ocr'ed)..
