Is fresh RMAN full hot backup snapshot required after database upgrade (10g to 11g)

Is 'fresh' RMAN full hot backup snapshot required immediately after major database version upgrade (10g to 11g) to be able to perform point-in-time recovery next week after upgrade?

In scenario where:

- L0 hot backup was completed just before the upgrade while database was running 10g

- after upgrade to 11g RMAN L1 hot backup snapshots are triggered daily (started by the script)

If, say, on 3rd production day after upgrade there is an outage that required restore from backup or for previous time point before that day, but after upgrade, would it be possible to use last 10g L0 backup files, recent 11G L1 backup files plus archive logs to restore the database ?
