Can I migrate a publisher to 2012 and have it continue to replicate to 2008R2 Subscriber without missing a beat

  I will be migrating our Production DB to SQL 2012 shortly (no service interruption using mirroring from 2008R2 to 2012). that part works well.

  But our Production DB is a publisher feeding a Reporting DB and I'm not clear if replication can pick up from where it left off after the migration or whether I have to re-build the publication / Snapshot from scratch and whether I can continue to use the existing 2008R2 distributor or have to switch to a 2012 distributor. Either way I would like to know the prescribed upgrade method from some experts who have given this a shot.

  Are there good articles (advice) on the subject?

  I'd rather not have to fully re-build the Transaction publication but could do that (including the lengthy snapshot) if that is the best/safest approach.

  In which case I might just re-configure the whole lot now to a 2012 Distributor now and make the new subscriber Reporting database a 2012.

  Thoughts?

  The distributor must be the highest version. then publisher, then subscriber.
