I’m pretty sure that there will be a site transer option for those who want to transfer a site from the Classic Editor to Editor X. Sorry, but I can’t give you an ETA.
By converging, I mean that Editor X will eventually support all features, APIs, vertical, and other Wix components. Both editors will be supported and enhanced.
As far as the Strip element and other site features, the best address for this is the Editor X community where you’ll be able to engage with other users, discuss design and site building, and find out what others are doing.
Have fun. I’m sure you will. Our feedback from the community so far is the designers are being blown away by Editor X and its elegant and robust design paradigm.
