3004 to 3006 wiped all DHCP reservations (YazDHCP) - settings restore did not fix

[Livin]

Today I moved from GT-AX6000_3004.388.8_4 to GT-AX6000_3006_102.4_0 and then noticed all my DHCP reservations were gone. I tried to restore the config from backup (which I just took minutes before) and that didnt help. I reflashed 3004.388.8_4 and all was fine again.
Is this a known issue and I missed it in the readme, or a bug? thx

Yes it's a known issue. You need to look in the threads of any third party addon scripts you're using to see if they're compatible with the new branch. They won't be mentioned in the firmware release notes as RMerlin has no control over them.

One should not try to restore a router.CFG file from 3004.388.8_4 on a router that has been updated to 3006.102.4 firmware. One may experience issues doing so due to the major changes between the two firmware tracks.

There are various methods and ways to backup and restore manual DHCP reservations between firmware versions. One is to manually copy files between the firmware versions, another is to use the addon YazDHCP develop version script. There is a known issue with YazDHCP non-develop version (v1.0.6) not properly importing in the 3006.102.4 firmware. The solution is to update to the YazDHCP develop version (v1.0.7).
If one is already running YazDHCP v1.0.6, make sure to update to the YazDHCP develop (v1.0.7) version by running the following:

/jffs/scripts/YazDHCP develop
/jffs/scripts/YazDHCP forceupdate

If one hasn't yet installed YazDHCP, they can install the YazDHCP develop version manually by running the following:

/usr/sbin/curl -fsL --retry 3 "https://jackyaz.io/YazDHCP/develop/install/YazDHCP.sh" -o "/jffs/scripts/YazDHCP" && chmod 0755 /jffs/scripts/YazDHCP && /jffs/scripts/YazDHCP install

If one doesn't want to use the addon YazDHCP script, one can manually backup or copy the files from the following location and restore them to the same location after a hard factory reset:

/jffs/nvram/custom_clientlist
/jffs/nvram/custom_usericon
/jffs/nvram/dhcp_staticlist

Save yourself future headaches by reserving a pool of addresses in DHCP then assigning those formerly reserved clients a static IP address.
