Hello Andreas, I just successfully performed in place upgrade from LTSC 2019 to 2021, all personal data have been kept.
Before the live upgrade, I've restored my PC into virtual machine and made a test there :)

To upgrade form one version of LTSC to another is very simple.
I log into the computer as an admin.
I uninstall the anti-virus as this can stop the upgrade from working.
I copy the Windows LTSC files to a folder on the desktop.
I run the setup.exe, and choose to keep all files and folders.
The upgrade runs, and it takes about an hour.
After its finished, I reinstall the anti-virus.

which windows ltsc files? you mean the ones from the ISO installation? could you share the information or link please?
The files from the ISO. You can copy them into a folder on the PC you want to upgrade, or mount the ISO ,and use the setup.exe to run the in-place upgrade.
I do not have a link for you sadly.
My Windows OS files are supplied by my employer.

Hello, I wanted to ask you what exact version of windows 10 LTSC you have (for example 1809 build 17763.2886) and what version of ISO was used to update. Thank you very much for your time and help. Greetings.
Greetings Mariano,
We have used 1607, and 1809, however any version of LTSC can move up to a more current version with an in-place upgrade. The build number doesn't matter, and will not be a factor in your upgrades. Your KMS key if you are using one should also be good for the new version of LTSC. Again the version of the ISO doesn't matter. We pull the files from the ISO, and run the setup.exe from a folder on the desktop of the PC being upgraded. The only thing I recommend is you uninstall your AV before you do the upgrade, and re-install it after you are done.
Currently we are upgrading to 21H2 LTSC.
Greetings Laurence. Thank you very much for your prompt response. I did the steps you mentioned without being able to update, the only option is to delete all programs and files from my system. I attach a screenshot. I hope you can help me update. Thanks a lot. Best regards.
The ISO used to update is 19044.1288.211006-0501.21h2_release_svc_refresh_CLIENT_LTSC_EVAL_x64FRE_es-es
I do not speak Spanish, however it looks like you are trying to upgrade using an evaluation version CLIENT_LTSC_EVAL_x64FRE, that won't work you need the full version of LTSC.

OK, @Tomas Antal more how did you run this update? Was it via Windows Update normal or how? I have LTSC 2019 and would like to update to 2021, but via Windows Update until the month of 12/2021 only Windows 10 1809 update came!
LTSC cannot be upgraded via WSUS or any other Windows Update method.
You must run an in-place upgrade to move from one version of LTSC to another.
Thank you so! I managed to update using the iso and ordering to upgrade! It worked normally here for me, thanks!
LTSC will never get automatic feature updates: that would defeat the purpose of using the LTSC in the first place.
LTSC: What is it, and when should it be used?
Did someone know how to get from 1809 to 21H2 version with the Enterprise Edition?

The Windows 10 upgrader tool does not allow to upgrade Enterprise Editions. It only works for Professional Editions or Home Editions. You must obtain an LTSC 2021 ISO from Microsoft. I don't think that is freely available.
If you wish to transition from LTSC to semi-annual Enterprise Editions, you must obtain the Pro/Enterprise ISO and start the installation from the command line and include the generic KMS key which is publicly available online:
setup.exe /pkey NPPR9-FWDCX-D2C8J-H872K-2YT43
