Update:
It successfully updated my site with redis and pagespeed… now let’s configure pagespeed 
I must say: totally speechless about how flawless easyengine switched my “setup” from w3tc to redis and pagespeed using the above command.
There was even a backup of database, nginx and webroot taking place automatically before any change were performed.
There is one tiny thing that wasn’t removed when ee dropped w3tc:
- there is an option in w3tc plugin that keeps bugging you in backend to activate w3tc edge mode. That’s supposed to unlock any prerelease-next-update-options in w3tc plugin. When agreeing to this, w3tc adds a line of code to wp-config.php
That line was not erased by ee when updating the site while dropping w3tc.
- There was a subdirectory in wp-content called w3tc something. I deleted it manually. Would be nice if ee could do this as well.
Other than that: nice job!
I am totally blown about ee being free and still offering this awesome community to its free users!
Thank you very much for that!
Will try and contribute to this forum as much as I can.
