new rules for connections between client and server in 10.7?
we will switch from Integrity 10.6 to 10.7 this weekend, but some testing-machines (server) will stay at 10.6. For this reason we tested to connect from a 10.7-client to a 10.6-server, but the client doesnt allow the connection. It states that client and server are not compatible. At the server we didnt configure any restriction, so from our experience the client should at most state that we could rollback the client or such things, but it simply denies the connection. With the admin-client, it connects (after two compatibility-messages), but it is hiding the config-section for workflows&documents.
Is it possible to connect a 10.7-client to a 10.6-server in any other way? At least to the workflows+documents-part? We want to avoid a parallel-installation of two different clients, because this is a mess for the users too
In general, cross release client-server compatibility is described in the Upgrading guide for the server's release version, at least since Integrity 10.3. The list of them is in this article. Also in general, clients are not backward compatible with server versions, but server releases are usually somewhat backwards compatible
To answer your specific question: The 10.7 client is not backwards compatible with the 10.6 server. In your particular situation, it seems it would be better to disable client upgrading when connecting to the 10.7 server until all of the 10.6 servers are upgraded or retired.
