Enlarging /boot and swap partitions

[Jonathan Wiebe <jonathan.b.wiebe@proton.me>]

I am going through the process of preparing my bookworm system for upgrade to trixie.

The following statement from section 5.15 of the release notes caught my eye:

• Before starting the upgrade, make sure your /boot partition is at least 768 MB in size, and has about 300 MB free. If your system does not have a separate /boot partition, there should be nothing to do.
  

My /boot partition is only 488 MB in size. Here is the output of lsblk:

NAME                  MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS

sda                     8:0    0 931.5G  0 disk

├─sda1                  8:1    0   512M  0 part

├─sda3                  8:3    0   9.3G  0 part

├─sda4                  8:4    0  23.8G  0 part

├─sda5                  8:5    0   9.3G  0 part

└─sda6                  8:6    0 851.3G  0 part /home/jonathan/Storage

sdb                     8:16   0   3.6T  0 disk

└─sdb1                  8:17   0   3.6T  0 part /media/jonathan/Borg-Backup

nvme0n1               259:0    0 476.9G  0 disk

├─nvme0n1p1           259:1    0   512M  0 part /boot/efi

├─nvme0n1p2           259:2    0   488M  0 part /boot

└─nvme0n1p3           259:3    0   476G  0 part

  ├─debian--vg-root   254:0    0  47.9G  0 lvm  /

  ├─debian--vg-swap_1 254:1    0   976M  0 lvm  [SWAP]

  └─debian--vg-home   254:2    0 408.1G  0 lvm  /home

As long as I am going through the process of resizing partitions I thought I would increase the size of the /boot partition to 2 GB.

I am also thinking of increasing my swap partition from 1GB to 32 GB (I have 32 GB of RAM).

So what I believe I have to do is:

1. Reduce the size of the lvm logical volume debian--vg-home by 32.5 GB.
   
2. Increase the size of the lvm logical volume debian--vg-swap by 31 GB.
3. Reduce the size of the lvm physical volume by 1.5 GB.
4. Move the lvm physical volume to the right (if that is the correct way to put it) to make room for the increased size of /boot.
5. Increase the size of the /boot partition by 1.5 GB.

(Do I need to move the lvm logical volume debian--vg-home before extending swap?)

Three questions:

1. Does the above outline make sense?
2. Can anyone point me to the documentation which will show me how to do this?
3. Am I over complicating things? Should I just backup my home partition and re-install from scratch with all new partitions and then restore /home?
   

Thanks!
