Hi, I am writing this thread as a reference for those intending to migrate from old Merlin versions to current ones. I recently did this with my RT-AX88U and all in all, the experience has been a great success.
I swapped my USB flash drive for a new one (the old one had started giving wear-related errors), and took the opportunity to migrate from version 386.3_2 (2021) and moved to 388.8_4. (2024). I did a dirty upgrade -although I had to recover/restore the USB contents to the new flash drive- and everything was correctly running afterwards.
The only minor nit I found has been /jffs which apparently 'filled' some days after and could not perform any writes. It had to be rebuilt by resetting the router and restoring from a known good configuration and jffs backup files. The culprit was finally a very big file residing in /jffs/.asdbk which took about 90% of the available space in /jffs. It was apparently a .tar file not yet completely built from some of my pre-migration work. No problems erasing it once the /jffs was rebuilt.
The new version looks amazing and the improvements and stability are very obvious and welcome. Thanks a lot to Merlin and the development team!.
So in summary, if you have not migrated your router in a few years, do not be affraid to do it. Just take care and good backups of everything!
