Document downgrade process

[zamazan4ik]

After reading the documentation it is not clear for me, how the downgrade process should be performed over the solution.

Could you please describe somewhere in the documentation:

• How to Cortex to the older version (hopefully with no downtime). Maybe near with a upgrade documentation?
• Maybe some compatibility policies and notes between versions

Thanks in advance!
