After having the luxury of upgrading Zen10 in a test environment over the last year, we now have 10.2 in production. Question: when 10.2.2 is released, can I upgrade the server first and then slowly upgrade the clients over a several week timeframe or do the clients need to be upgraded immediately after the server install. Any issues if the server is on 10.2.2 and the clients on 10.2?
