Excuse me for resurrecting this thread, but I'm trying to do the same thing. I'm running Radiant 0.9.1 with the Archive, CopyMove, FancyBox, Navigation Tags, Paperclipped, Ray, Reorder and Settings extensions. I copied the MySQL DB and the radiant folder to new server. Then began following instructions to upgrade. I got a bunch of errors/alerts in step 7 "bundle exec script/server". There were several Gem::SourceIndex notices about things being deprecated. Then I got a whole bunch of load errors. I tried it again, making sure to follow the instructions exactly on the web page, but I'm still getting these errors. If I ignore the errors and continue with the instructions, I get to the step "bundle exec rake radiant:update" and then it aborts because it didn't know how to build the task radiant:update. Could someone please help me figure out what I'm doing wrong? I'm going to need some hand holding with this. If there's another way to migrate this site, I'd be happy to give that a try. Thanks for your help.
