The wsconfig "update" feature should back up changed connector files, similar to how a remove does| View in Tracker
When we run the wsconfig "update" feature (in the wsconfig UI), that simply updates the needed files (usually just the isapi_redirect.dll for IIS, or mod_jk.so for Apache). While it's simple and fast, a problem happens if it turns out the connector update has a problem. Then there's no easy way to revert back to the old connector file(s). At least when we "remove" a web server connector (with the wsconfig UI, since CF11), we are offered the option to let it backup the current connector files. The "update" feature should offer the same. Or at least backup what the update CHANGES, whether it's just the dll or .so file, or perhaps also a properties file. I don't know if the update may ever change a properties file, but if it did, that could lose customizations that a user did to that file, and again this backup of whatever the update changes could be used to detect and/or recover from that.
