CMK version: check-mk-raw-2.2.0p1_0.focal_amd64.deb
OS version: Ubuntu 20.04 focal

Error message:
The central (Version: 2.2.0p1, Edition: CRE) and remote site (Version: 3.5.1, Edition: unknown, License state: unknown) are not compatible. Reason: Central site is version >= 2.2 while remote site is an older version, please update remote sites first

How to fix this?

As mentioned in the error message: please update remote sites first

New central site and old remote site will not work!

Hi @air-vison

quoted from the Update documentation

There are two different procedures for performing an update of all sites included in a distributed Monitoring (https://docs.checkmk.com/latest/en/distributed_monitoring.html):

* Stop all sites, perform the update of all sites in a bulk action, and then restart all sites.
* Under strict conditions, a *mixed operation* is possible for a certain period of time, in which the remote sites are updated first, following which version equivalency is restored with the update of the central site.

You will either have to upgrade your remote sites or downgrade your central site.

We have extended this for the 2.2 branch of the docs. Technically also applies for 2.1.
