Upgrade Sequence Mountain Lion/PD8 to Yosemite/PD10

Hi, I am finally about to bite the Bullet And Upgrade to the latest versions. (I am deading this). I have just purchased the PD 10 Upgrade, I am currently running Moutain Lion 10.8.4 and Parallels 8 and am about to upgrade to Yosemite 10.10 and PD 10 on a MacBook Air (mid 2013) I am thinking I shoud Upgade to Yosemite first and then to PD 10 next. Is that correct. Will my exsisting Windows 7 VM configuration be left intact or will I ahve tp reset up VM. Are there any other Tips/Issues involved to get a sucsessful upgrade.
Forgive me if this has already been disscussed. I searcged but could not find anything directly addressing this.
Thanks in advance for any help

Help.. I know this was a Dump question. But has no one got the anwser.
Do I upgade to Paralles 10 while on Mountain Lion and then to Yosemite or
Do I Upgrade to Yosemite first and then to Parralles 10.

It's not an important question because the order is fairly irrelevant, but I would update Parallels first, simply because PD10 is compatible with ML, so it would be fully functional even before upgrade to yosemite.

 

Thanks, I will do that.
