USB swap for M.2 SSD with "soft" option?

[xmanyes]

Hi,

I see my USB is probably failing with some files locked and no way to make updates for a few addons in amtm... So I saw several posts with the same problem and all suggest either replacing USB or, better version, SSD (M.2) 256Gb. As I have 4 routers (main AX58 + 3 older in AI mesh) and 38 devices, parental supervision, setting up everything from scratch would be a major PITA... MAJOR! Probably a day or two with gradually workable solution for 2 families, which means I will be eaten alive in the process by each and everyone...

So I am asking, if there is any "soft" solution to just swap the USB for 256 Gb M.2 SSD and somehow continue with the existing setup outlined above? How & what are the best steps? What size should be the swap file and are there any other suggested settings that should be specifically taken care off for, hopefully, some peace of mind?

Luckily for now only few minor amtm addons are locked (connmon & scMerlin, which I cannot even uninstall due to a lock) and even if amtm addons would need to be re-created/re-installed, it shouldn't be any major issue, except maybe Adguard, I have "tons" of settings that I am not sure how to backup/restore...

Tips here highly desirable, thank you community & wish everyone happy holidays and New Year!

Maybe see if the BACKUPMON addon script may be of use for what you seek or desire.

BACKUPMON - BACKUPMON v1.9.1 -Oct 28, 2025- Backup/Restore your Router: JFFS + NVRAM + External USB Drive! CIFS/SMB/NFS! (Available in AMTM!)

BACKUPMON v1.9.1 Released October 28, 2025 First off -- HUGE thanks to @Jeffrey Young for sharing his original backup script. His script is the main engine of BACKUPMON, and all credit goes to him! BACKUPMON is simply a wrapper around Jeff's backup script functionality, adding easy-to-use...

Edit to add: From that BACKUPMON link:

Use-case: BACKUPMON was designed to backup from, and restore to an already configured router from an external network resource, given a situation of a corrupted USB drive, botched Entware environment, or other general corruption issues. It can, however, also restore you back to a previous state if you decide to completely wipe your router or external drive from scratch. You can use it to move from one external USB drive to another... say, upgrading from a flashdrive to an SSD! You could also use it to restore your environment to a similar router if your old one dies, and you pick up the same model + hardware revision + firmware level as a replacement (at your own risk).
