Can I continue to use an older server while updating to the latest client version?
In most instances, the new XA client will continue to function with older XA server versions. However, additional features provided by the client may not fully function without the latest server version. For example, the HCIDeploy Publisher management application from 4.11 will not function properly unless the server is 4.11 or higher. A 4.10 HCI Deploy publisher will also not correctly function against a 4.11 server - it must remain pointed to a 4.10 server. A 4.10 HCIDeploy client will still pull updates from a 4.11 server, but cannot be managed by newer tools, and the 4.10 management tools cannot be used to maintain the server. In the case of the XA toolbar, you cannot use the 4.10 client pointed to a 4.11 server - you must use a 4.11 client pointed to a 4.11 server and leave the 4.10 client pointed to a 4.10 server. The data changes are incompatible between versions.
