> SENTRY-1480 implemented a command-line tool to migrate Sentry permissions
> from 1.x to 2.x. During upgrade testing I found a bug in the migration
> process where the pre-upgrade permissions are deleted. Specifically following
> permission was configured on Sentry v1
> {noformat}
> collection=*->action=*
> {noformat}
> After the migration, following permissions were available on Sentry service
> {noformat}
> admin=collections->action=*
> admin=cores->action=*
> {noformat}
> Note that the original permission is missing. From the following log snippet
> of Sentry service, it looks like the original permission was incorrectly
> revoked.
> {noformat}
