Hello!

I am upgrading my RT-AC68U router to RT-AX88U Pro. Merlin 388.2.2. Saved settings on RT-AC68U and restored on RT-AX88U Pro.
Lost:
1. Login and password for Internet access.
2. Routing for the OpenVPN (Allowed Clients -> Common Name(CN), Subnet, Mask).
3. MAC filter list.
4. Manually Assigned IP around the DHCP list.


Can I transfer MAC addresses and DHCP settings from RT-AC68U to RT-AX88U Pro?
Do I need to clean anything after this restore?

You may have bricked your new router. Do a hard factory reset and then manually configure your new router. Do not use another config file!
 
I wouldn't attempt migrating settings between AC68U and AX88U Pro. They are four generations different hardware routers. Reset the new AX88U Pro and configure manually with copy/paste settings from screenshots. Otherwise "everything works" is not guaranteed in a long run.
 
I understand that you need to do a reset. Is it possible to export some settings? For example:

From RT-AC68U
Code:
# nvram get dhcp_staticlist
# nvram get wl_maclist
# nvram get wl0_maclist
# nvram get wl0_maclist_x
# nvram get custom_clientlist
# nvram get sshd_authkeys
# nvram get vpn_server_ccd_val
# nvram get vpn_server_ncp_ciphers
...

To RT-AX88U_PRO
Code:
# nvram kset ...

If yes, what is the syntax of kset?
Code:
# nvram kset filter_lwlist=<>445>>>TCP ...
- error

What do I need to export for an OpenVPN server?
 
The correct command is "set" not "kset", and you need double quotes around the contents, e.g.
Code:
# nvram get filter_lwlist
<>>>445>TCP
# nvram set filter_lwlist="<>>>445>TCP"
The OpenVPN server settings are spread across numerous nvram variables as well as files in /jffs/openvpn.

I would make a screenshot of settings and export the certificate only. On the new router configure the server as before and import the certificate.
