Hi Zatom,
We did a similar upgrade in my environment and had some issues with the changes to the way Chrome attaches and detaches. I think BP Support fixed it and provided updated files in the 6.10 release package so you should be ok now, but we did struggle with it for a while. Detach didn't always work the first time so we had to use retry loops to confirm detach. Also, there are a lot of changes to functionality (for the better!) so as other people said, definitely look at the release notes. You might also see some of your wait stages now throw "errors" in the error checker, but if you just recreate them exactly as they are they'll work. I also think the "Automatically resolve" button works, too, but it's been a while so I'm not 100% sure.
Hope this helps and good luck!
