tmsh on 10.2.1

I'd suggest, with the availability of multiple volumes, that this is a highly time consuming and wasteful approach. Regarding v10 to 11 upgrades in general;

Before you consider upgrading from v10 to v11 you should consider the following and change your configuration accordingly;

•Replace the matchclass Command in any iRules with the class match Command.

•Remove any global variable references using :: (double colon) or $:: as these are unnecessary in v10 and not supported in v11.

•Note that Class/Data Group configuration formatting changes; you shouldn’t have to do anything but keep this in mind as a possible troubleshooting target.

•Note that Node configuration formatting changes; you shouldn’t have to do anything but keep this in mind as a possible troubleshooting target, it seems to be a common cause of issues.

•Ensure all service and protocol specifications in your configuration files use a port number, not a service name.

•Anything configured in an Administrative Partition that doesn’t have the path specified in the v10 configuration files, needs that path to be specified in v11; edit your files as necessary.

•The parent id command becomes parent name in v11 and may prevent the configuration from loading post upgrade

Regarding any possible changes, I'd suggest you carefully look through the release notes for the major version you plan to upgrade to as well as the latest for your major version: http://support.f5.com/kb/en-us/products/big-ip_ltm.html.
