in regards to these steps as advised to look into with caution especially when dealing with any of your own larger amounts not meant for immediate liquidity and transactions, these are usually to secure backups and would be migrating channels while they are open, as detailed on the risks you should not have any previous instances running at the same time with the same LND aezeed seed phrase.
While preemptively optimizing for fee environments and for lightning node operators, setting the best sensible defaults and options in their lightning config file seldomly changes. I assume enterprise nodes also preemptively close their channels then re-open them, or have action plans in case of catastrophic failure.
For PCs and laptops I wouldn’t advise to run on as they go into standby mode, NUCs (Next Unit of Computing) like the Umbrel Home optimized to be an always on personal server with low power-draw are better in this regard and specifically have automated features that will allow you to restore your channels in the interface with just your seed phrase and this UI has continuously been improving so you can manage all these settings right in the settings page without having to constantly mess with editing the lnd.conf text file when adjusting certain lines with a setting, which is not recommended since here are these settings to manage all those easily now like this: https://x.com/umbrel/status/1562099972547690501
