I am currently using 2010 v3 in my projects. I would like to install 2011 v1 and start using it. But, would like the option to easily revert back to 2010 v3 if needed. Is this possible? If so, do you have some guidance? Perhaps I'm overlooking it, but I haven't seen anywhere this is covered in the documentation.
Thank you for the prompt reply!
You can have 2010.3 installed side-by-side with 2011.1. The version utility will help you upgrade to 11.1, and once it succeeds you keep the backup folder contents that's created during the upgrade, you can use them to move back to the project how it was in 2010.3.
