Two things to note. 1) The default persistence adapter in 5.3.1 is different from 5.1.0 so you will need to drain all persistence destinations before migration or explicitly configure a matching persistence adapter to maintain the existing state. 2) There have been a couple of wireformat (the client broker protocol version) updates between 5.1.0 and 5.3.1 so you will need to update your clients activemq jars to take advantage of the features/fixes that precipitated these wire format changes. If you do not, negotiation will result in the lowest common denominator feature set being used.
