If there is please give full tutorial or specified thread.

This could work but i wanted to know how to switch from 1.13 modded lobby to a 1.11 lobby but not this method of having both installed.
is there a way to already have a 1.13 CL patch then
1)on 3.55 delete 1.13 pkg
2)install 1.11 pkg
3)put 1.11 patch and delete default_mp.self
4)data transfer
Would this method work?

ok i see so do the mw2 update then delete the default_mp.self then you are online on 1.11 but it says 1.13 but people have to bypass to join you
