There is no issue mixing it up. However IAP-205 is much older than the rest and is not supported on the latest Instant version like 8.x
So in this cases you need to go with the last version that is supported by the olderst AP model.
The latest Instant version that IAP-205 is supported on is 6.5.4.x where as IAP-305 and IAP-315s can use version 8.5
