How to migrate RT-AC86U to RT-AX86U-PRO?

[BosseSwede]

Configuration problem somewhere?
I have now replaced the old router with the new RT-AX86U Pro and checked it out.
Mostly it does work Ok including the connection via VPN back to the home LAN.
But I have found a few items that are non-working:

1) Front status LED:s black
The row of LED indicators on the front of the router are all dark so I cannot read the current state of the system. Is there a setting to switch off the LED:s that I might have accidentally activated?

2) NFS shares back to home LAN not working
I have two RPi4 devices running OSMC Kodi here and they use the main video store on my home server via NFS.
I had set up autofs on the RPi4 devices and it worked just fine before the router switch. But now the RPi4 cannot connect NFS to the ubuntu server back home using autofs, so I switched it to a connection managed in /etc fstab instead.
I had used connections via fstab earlier so I activated the line there which used before I discovered autofs.
But when I ran this I received an error message:

$ sudo mount -a
mount.nfs: access denied by server while mounting 192.168.119.251:/home/bosse/www/VIDEO

This has worked just fine on all of my earlier Kodi setups, just not now...
In fact it seems like all my nfs connections back home fail with this router....

NOTE:
I also have a video source on my home LAN which uses Samba for sharing. It is located on a Synology NAS on my home LAN and that works just fine.
So there must be something about the networking change that has caused my home ubuntu server to start refusing connections.
What can it be and how can I fix it?

Yes the firmware has an option to turn off the LED's. You may have inadvertently hit the button on the right side of the RT-AX86U Pro router to disable the LED's.
[Wireless Router] How to turn ON/OFF LED light of ASUS router?

In the router GUI go to AiMesh > Topology > Management > LED
If using Asus-Merlin firmware there is also an option to turn off the LED's under Administration > System > Enable LEDs.

Personally the LED's are so ridiculously bright on the RT-AX86U Pro that I have them disabled on mine.

Edit to add: I may have missed it but what firmware are you running on the RT-AX86U Pro?
On the NFS issue, first step is to ensure all IP address used for mounting are correct and that you can ping each of the clients you are trying to mount.

FINALIZING
Today I switched on the new router and managed to get "almost" everything checked out OK.
But these items occurred:

1) No LED light
For some reason all of the indicator LED:s on the front of the router have been switched off so I cannot see the state of the router by looking at them. What could have done this?
The router seems to work OK apart from this and the LED:s were shining before I carried the router to the living room..
Is there a setting I might have touched which disabled the LED indicators and if so where is it?
Edit:
STUPID ME (with old eyes too): There was a button on the side of the case which read LED OFF/ON or similar hard to read in dark gray on light black...

2) No access to NFS shares on the remote server
I have several devices (media players etc) which use data from the server in my home LAN.
So I have used the router built-in OpenVPN client to connect the summer cottage LAN to my home LAN (the OpenVPN server is running on my main Ubuntu server at home). This has been running fine with the old RT-AC86U router's built-in OpenVPN client.
So I did not expect what would happen...
The config was completely transferred to the new router and an OVPN file uploaded to handle the VPN connection.
But the VPN connections on all of my devices here failed.
After 6 hours of troubleshooting with the help of ChatGPT we finally found what was the problem and it was that the ASUS was running ASUSWRT 3.0.0.6 (the “Next Gen” firmware line) where they have introduced NAT translation through the VPN client without any way to switch that off!
So I had to add an extra client IP range to the server side exports file with the ASUS set IP value.
This took the better part of today to figure out once I had started the new router7 hours ago.
Everything else seems to be A-OK and VPN is now also running.

PS: And I am running the stock ASUS f/w updated a few days ago.DS
