During an automatic update procedure,
the system updates each of the canisters systematically. The automatic method is the preferred procedure for updating the
code on the canisters;
however, to provide more flexibility in the update process, you can also update each canister manually.
During this manual procedure, you prepare the update, remove a canister from the system, update
the code on the canister, and return the canister to the system. You repeat this process for the remaining canisters until the last canister is removed from the
system. Every canister must be
updated to the same code level. You cannot interrupt the update and switch to
installing a different level. After all the canisters are updated, you must confirm the update to complete the process. The confirmation
restarts each canister in
order and takes about 30 minutes to complete.
