SCCM upgrade from 1802 to 2006
I am trying to upgrade the SCCM version. The current SCCM version is 1802. The SCCM server is not exposed to internet (due to security concerns), I have to go with offline upgrade method.
The latest version available now for SCCM is 2006. I have searched on MS articles for the upgrade process from 1802 to 2006 but seems that I cannot direct upgrade it from 1802 to 2006.
I have to firstly upgrade it to 1906 and then from 1906–>2006.
I have found some in-place upgrade options which I can use to upgrade till 2002 version but not sure whether I can do it from 1802 directly.
Please let me know if this is the correct approach or I can plan it in other way.
