Deactivation questions. Temporary switch?

Hi everyone. I'm going away for several months, and I want to be able to use my creative cloud software on another desktop for this time (I already currently have it installed on a desktop and a laptop). However, I have some questions/concerns about the deactivation and installation process.

1) Do I need to actually uninstall the software before deactivating to be able to install on a new machine, or is deactivation sufficient?

2) Is deactivation permanent? Once I deactivate the software on my current desktop (2011 iMac) can it no longer be activated?

Essentially, my question is whether I can temporarily switch computers. I know that creative cloud can be installed on two machines, but I already have it on a laptop, so the real question is if I can switch desktops for the time I'm away.

Hopefully I've made my questions clear. Thanks in advance for any responses or insight you can give on this topic.
