I have some older files which I haven’t gotten around to upgrading until now, and Xcode Beta says I need to migrate them with an older version of Xcode.  Right now, I still have that older version, but once Xcode gets upgraded in the fall it will no longer be possible (or is it a temporary limitation)?

You can also get every previous version of the Xcode IDE[1] via Apple’s developer web site, and use the appropriate Xcode on an OS on which it’s supported to do whatever conversion you need.
