Master with 2 Slaves

We currently have a Master - Slave setup were all databases are being replicated. We are looking at moving out one of these database from this cluster, and would like to perform this with minimal downtime… The idea is to setup another slave for this master and use the replicate-wild-do-table=databasename.%

Master = 5.5
Slave 1 = 5.5
Slave 2 = 5.6

I would like to confirm if this configuration is supported before we proceed.

Thanks

yes this configuration is ok, you can have higher version as slave and lower version as master.
