I'll try to upgrade a CHR with new firmware, but on reboot, il make an error.
Thank some much.
Sorry but the license is active and not the free version, the license is P1.The error message says it all. Once your trial period is over you can no longer upgrade your instance. You should have bought a suitable license (or switched to the free license, in case you are fine with its limitations) before the trial ends. See CHR Licensing.
