I Think I'm Ready!

Hi Everybody! I think I'm ready to get rid of PT10 for good. Ive had the coinstall and all I ever use is PT11 anymore. Question is .....

1. What is the proper way to delete PT10 from my imac with mt. lion 10.8.5 ?

2. Is it doable without any freaky/sneaky PT issues after the fact?

3. Im just thinking itll make my computer leaner/faster? less stuff to recall?

4. I can just import whatever sessions I have in PT10 into PT11 and continue on?

Thanks!
