replace Theme 7.9 with Theme 7.10 in suitecrm 7.9.x

Can I replace Theme 7.9 with Theme 7.10?
I want to use 7.9 with the theme of 7.10!
Can this be a problem?

That is not possible.

Why do you want to stay with 7.9?

until yesterday in the download link version 7.10 was with the message:
“NOT for production”

Can I already use version 7.10.0 in production mode?

I upgraded to 7.10, GONE EVERYTHING RIGHT! THANK YOU! :lol: :lol: :lol:
