To make sure, 10.11.6 won't cause issues, I installed 10.10.5 to the external SSD, then restored from Time Machine and finally upgraded to 10.11.6
After checking, that I have no issues, I upgraded the internal SSD installation to 10.11.6 too.

These test installations to an external HDD / SSD can avoid a lot of issues, because you have an instant fallback without hassle ... the test though needs more time, but is absolutely safe. But cloning software would speed this up.
