If you do ever want to try to make the switch again, you might try the 'Auto Tab Discard' extension. It lets you customize how tab unloading works. I had 2755 tabs open without breaking a sweat (down to 1093, woo!). Starting the browser will only load the last active tab and, as you continue to work, your older tabs (depending on your setting) will start to get unloaded. I want to say this is a feature of the browser itself, but the extension (add-on, whatever we call them now) gives you a lot more control. As for session migration, maybe an extension like 'Tab Session Manager' will help? It supports several different formats, so surely one of those formats is something that Chrome can export. That would let you move everything in one fell swoop, at least.
