Yep! Looks to be out of stock at the moment, but framework sells it directly. https://frame.work/products/battery?v=FRANGWAT01

I ordered a 7640U (hopefully shipping this week), because I don’t need the extra processing power. Planning to upgrade to the 61Wh battery afterwards, though, and hopefully figure out an enclosure to turn the 55Wh into a power bank.

I know this is probably not the answer you’re looking for, but at my work we never even do in-place upgrades from one version of rhel to the next. Always a fresh install on a new server, then migration of each service.

If that sounds painful, it could be a good opportunity to dabble in some configuration management (like Ansible) or at least thorough build docs of how to get a bare server into the state you want.

The steps would basically be:

1. Fresh OS install on new server
2. Install each application and get it running.
3. One by one, stop the application, copy data (files and/or databases) from old server, start application, troubleshoot until it’s happy
4. Switch DNS to new server
5. Decommission old server

It’s a bit harder if it’s a physical machine and you can’t spin up a new one simultaneously. With that, you just have to make a backup to an external drive and schedule some downtime.
