I’d probably add the wildcard in case of remnants of upgrades

good idea, thanks Ed! i updated my post.

With this change, I am seeing an overall reduction in memory usage by about 4%. Well done.

yes i did upgrades on dual containers on one server a couple of weeks ago (on a russian server too). no issues at all but make sure you have enough disk space first.

Thanks Lilly, did the upgrade earlier and it all seems to have gone ok
