Preparing for Debian 13

[Default User <hunguponcontent@gmail.com>]

Hi.

I currently run Debian 12 Stable, amd64. 
Unexceptional single-user SOHO setup on a relatively current 
(2023) low-end Dell laptop. 
Intel Core i3 processor. 
8Gb ram.
UEFI booting. 
Internal nvme SSD, 256 Gb, for mass storage. 
Partitions: 
nvme0n1     259:0    0 238.5G  0 disk 
├─nvme0n1p1 259:1    0   512M  0 part /boot/efi
├─nvme0n1p2 259:2    0  23.3G  0 part /
├─nvme0n1p3 259:3    0   9.3G  0 part /var
├─nvme0n1p4 259:4    0   977M  0 part [SWAP]
├─nvme0n1p5 259:5    0   1.9G  0 part /tmp
└─nvme0n1p6 259:6    0 202.6G  0 part /home

Note: 10 Gb for /var is barely adequate. I have to 
periodically do surgery to cut out the built-up bloat there.

Since Debian 13 should soon be released, what should I be doing 
ahead of time to prepare for the upgrade? For me, upgrading is 
always a major hassle, so I try to make it as easy as possible. 

OT rant (probably irrelevant): 
The laptop does NOT support virtualization. The DOES, but the 
BIOS does NOT! 

Apparently the tightwads at Dell are punishing me for being poor. 
"Hey dude, you've got a Dell!" Sorry to hear that . . . 

(Grrr . . .)

Advice?
