I was following the guide at https://docs.travis-ci.com/user/migrate/open-source-repository-migration#migrating-a-repository and could not see any option to migrate my repos building on travis-ci.org as described in the guide. After following other forum suggestions, logging out and in, clearing cookies, using other browsers etc. I finally saw my repos in a “migrate” tab, but with this message “Migration is not available for this account”. Fortunately due to the above comment, after over one hour of searching, reading, and experimenting it finally became clear that I have to click “Sign up for the beta” before I can take any of the other steps. The migration guides are about two years old and migration is now essential to avoid slow builds, so it’s not obvious that migration and building open source on travis-ci.com is still considered a beta feature. The guide does have text near the beginning saying to sign up “If you’d like to become a beta tester” but at this point most people making the migration do not sense that their beta testing something. They are just switching to what is perceived as the “main” stable service.
I know a few people who started experiencing slow builds on .org and wanted to migrate to travis-ci.com, or who have been advised to migrate by colleagues, but were confused and just gave up or migrated to other build systems. Please consider changing the text “You can now have all your public and private repositories together at travis-ci.com / Sign up for the beta” to something like “Enable migration from travis-ci.org to travis-ci.com”, and changing the text “Migration is not available for this account” to something like “please enable migration on your travis-ci.org profile page”.
