According to https://trac.sagemath.org/ticket/30406#comment:15
trac continues to be running after migration to keep links to trac alive. Then do we really need to migrate (copy) tickets to github once and for all? I guess that the migrated tickets would be full of broken links internal or external. No? Instead of having broken copies, why don't we keep the old tickets in trac, and start only new tickets fresh in github. The release manager would just declare to accept only PRs from github and reject branches of tickets from trac. Then people would just start to make new tickets in github mirroring tickets in trac. Gradually github will replace trac in all development activities, without broken links. No? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
