Question on re-homing router nodes to a new conductor. We have a write-up on Interchange, but it seems outdated.

Can engineering please provide feedback on rehoming with Conductor on release 3.2.4-2?  Here is what I'm thinking:

1. Export running config from current conductor, then import and commit it on the new conductor.
2. Drop into Linux shell and run 'install128t' script on each node being re-homed. Supply the new conductor's IP address(es), when inside the utility.
3. Restart salt-minion. The rest should be done automatically. Please comment. Are there any caveats if some of my router nodes are still running 3.2.3 during the re-homing process?

Hello Gene,

Yes, the previous how-to guide was based on 3.1 and there have been improvements made into the product since then to make this process much easier. The steps you outlined will get the process done, but I would recommend just a re-initialize instead of re-install in step 2 to minimize downtime and preserve local router info (config, analytics, etc.). Here's the updated steps to re-home a router to a new Conductor:

1) Get new Condcutor online with existing config. Typically I use the same method you discussed:

-Export config in GUI in old Conductor

-Copy backup config to new Conductor

-Import config in GUI in new Conductor

 

2) On the router to rehome:

-Stop 128T

sudo systemctl stop 128T

 

-Run the re-initializer and this is where you point to the new Conductor address

sudo initialize128t

3) Once the re-initializer is complete, just restart the salt-minion and our Automated Provisioner should kick in and finish everything up in a matter of minutes:

sudo systemctl restart salt-minion

Also of note, we will work to get the previous how-to guide updated to reflect more current best practices in the near term as well.

Thanks, Adam. Good catch there in my proposed step 2. Actually meant to say initialize128t, but typed install128t instead. Also, thanks for the more detailed commands to get the steps implemented!

Update: I used this three step process last night and this morning on three different routers, and it worked without an issue. Thanks again!
