Can we change the name of rpool?

Question

Can we change the name of rpool? Do we have to create a new BE(Boot Environment)? Can anyone tell me the complete process?

To change the name of the pool, you should merely import it (which implies of course previous export) with the new name; however for root pool this requires the single mode and/or booting up from the alternate zfs-capable source.

It's also worth mentioning that, as you were told, there's no obvious reason to rename the root pool: yours is named after the Solaris naming convention, which I personally find fancy and cool.
