After upgraded to version Beta 7.1.1 via
memsql-deploy upgrade --version dev:153ba2f3-aae3-47c5-aa6f-56d546aa8ead

My MemSQL got this error:
FATAL: Cannot upgrade existing node to version 7.1.1 beta. This is a non-production version of MemSQL.

How I can solve this error?

You can’t upgrade an existing cluster to the 7.1 beta. The 7.1 general availability release will be out very soon. It will let you do that.
