https://docs.mailman3.org/en/latest/migration.html We currently run Mailman 2 which is not supported in Debian/Bullseye which will freeze soon. So upgrading will force an upgrade to Mailman 3 (which is a good thing anyway), above are the upgrade docs. One thing to note is that URLs for archives will change, is this a problem? https://etbe.coker.com.au/2021/01/12/psi-cgroup2/ I've already started upgrading the LUV server to Debian/Bullseye, the above blog post shows one of the things I'm doing to take advantage of new Linux and systemd features. To get some of these things working well before the freeze of Bullseye I need to have some real servers running the latest code. I would like to get the upgrade done in the next few days. I don't anticipate this causing any inconvenience as the lists have been very quiet recently. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

I don't recall messages on the list (at least recently) that contain links to messages in the archives. So, it probably isn't a problem, as I doubt it will result in broken links.
I tried to do a similar Mailman 2 -> 3 upgrade and ended up rolling back to Mailman 2 even though it is unsupported. Mailman 3 has much higher minimum memory requirements than Mailman 2. If the server is memory bound you might run into some trouble. Cheers, Pete On Sun, 17 Jan 2021 at 04:03, Jason White via luv-main <luv-main@luv.asn.au> wrote:

Thanks for the information, are there any other problems you encountered apart from RAM use? The system running the LUV VM has 48G of RAM and has 24G of that allocated to VMs. There are some things running on the Dom0, but no fraction of 24G. I could easily add more RAM to the LUV VM if needed. As an aside RAM is getting significantly larger and cheaper. DDR4 DIMMs are a maximum of 64G while DDR3 DIMMs are a maximum of 16G. Servers with DDR4 tend to have about 4* the RAM of servers with DDR3. Hetzner (the company hosting the hardware that runs the LUV VM) doesn't offer new servers with less than 64G of RAM. I recently got a quote on hosting in Australia and was offered a blade server with 256G! Recently a client needed a PSU and a fan replaced in an IBM rack mounted server, they bought a server on ebay for $200 which was cheaper than buying the parts they need new. The $200 server has 64G of RAM. RAM is getting ridiculously large. https://cloud.google.com/compute/vm-instance-pricing The GCP offers VMs with as much as 11776GB on a special deal! But for the regular VMs (which offer deeply discounted "preemptible" prices) the largest seems to be just under 1TB of RAM. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
