You can update Transfer Appliance software if you've ordered an appliance that supports online transfer.
Before you begin, follow the instructions to prepare a service account key for online transfer.
Updating the software also restarts the online transfer.
Run ta update to update the software listed below:
- Operating system
- Binaries
- Docker containers
You can update each item individually by passing the appropriate flag(s)
to ta update:
ta update --os --binaries --containers
A successful response looks like the sample below.
Updating containers on the appliance... This may take several minutes to finish... Online containers are updated successfully on the appliance. Updating binaries on the appliance... This may take several minutes to finish... Binaries are updated successfully on the appliance. Updating Operating System on the appliance... This may take several minutes to finish… Operating System was updated successfully. Appliance will now reboot in a minute. The boot up process after reboot may take several minutes.
If online transfer isn't enabled, the following sample response is returned:
Appliance is not configured for online mode, thus not updating online containers. Updating binaries on the appliance... This may take several minutes to finish... Binaries are updated successfully on the appliance. Updating Operating System on the appliance... This may take several minutes to finish… Operating System was updated successfully. Appliance will now reboot in a minute. The boot up process after reboot may take several minutes.
OS rollback
If the updated operating system is problematic, you have the option to do an OS rollback. An OS rollback allows you to rollback the OS of the appliance from the updated OS to the OS before the update.
- An OS rollback requires an OS update to have taken place already.
- An OS rollback requires the version of the current OS to be greater than the version of the previous OS.
- An OS rollback can only be done once for every OS update.
You can perform an OS rollback by running the following command:
ta os rollback
A successful response looks like the sample below.
Operating System was rollbacked successfully. Appliance will now reboot in a minute. The boot up process after reboot may take several minutes. Please do not run any additional commands until the appliance has finished rebooting
