Yes, you can do that.
First step would be to take backup of your current Lightroom 6 Catalog.
Then, follow these steps:
1. Open the same catalog
2. Go to File menu > choose Import from Another Catalog
3. Browse and select the first catalog that you want to merge with this one
4. Choose "Discard Upgraded Catalog After Import" [This will upgrade your older catalog and will not save its upgraded copy]
5. Select the suitable options and import
6. Repeat the process for all other catalog which you want to merge with the main one.
Let us know if you face any difficulties.
Thanks for your response.
I took all the steps you described - but I of course first made a backup
of my Lightroom folder - but it did not work out as I hoped for.
Merging all the older catalogs into the Lightroom 6 catalog took about
10 hours (but of course that was no problem wit a total of nearly 40.000
pictures in the catalog) and I got during that process several
(certainly more than 60 but I did not fully check: see later) tags in
the final catalog that I did not had (or had anymore) before and I was
asked to import many pictures (nearly 400) that were not in the last
general Lightroom 6 catalog.
After I finished the process and checked several large badges of
pictures with the same tag I found in the catalog links to pictures that
had no corresponding digital negative anymore, as I at some moment I had
discarded that picture / digital negative. But the link somehow still
existed in earlier catalogs...
The most important thing however was that older pictures still opened in
the framework of the older Lightroom versions with sliders / options
from that version and not from Lightroom 6.
As I started all this to be able to process my older pictures too under
the options / possibilities of Lightroom 6 I have discarded the merged
version of the catalog and re-installed my (clean) backed up Lightroom
I tried but I keep it now as it is, as I only seldom have to re-edit
pictures from 2006 or 2007...
Still many thanks for trying to help me!
Best wishes, Ton

I have a LR6 stand alone version on a Win7 64 bit workstation.
I use Lightroom from the first version and have still all the old catalogs in the standard Lightroom folder:
For some reason today I had to edit several pictures I made in 2006 and I got under "develop" in LR6 the dialogues from an earlier version of LR; I don't know which version.
It sounds like you are referring to the 'Process Version,' which is 2003, 2010, and 2012. In the Develop module go to the Camera Calibration panel (bottom panel) and next to Process: select 2012, which is the latest Process Version.

I looked at the forum into discussions under "upgrade" and "merge" catalogs but I still am not sure what I can / should do, WITHOUT losing tags (as all my pictures are tagged in more than one way), lose development settings or losing pictures.
So my question is: Is there a safe way to upgrade or merge the catalogs from the older versions of LR to LR6, in such a way that I can edit the older pictures with the editing tools available under LR6?
Each time you install a new version of LR (2> 3> 4> 5> 6) it asks if you want to upgrade the previous version catalog. This brings over ALL of your edits added in the previous versions and links to all of the image files on your hard drive.
Your previous version LR 2, 3, 4, 5 Catalogs and Previews Folders are "obsolete" and of no use. If you are sure all pictures you imported in previous versions are present in the LR6 Catalog you can safely delete them to free up hard drive space. If you have any other questions or concerns please let us know.
