Moving Networker 8.2.4 from one VM to another VM with a higher RHEL OS version
Hi,
If the operating system is end of life on a Networker server specially if its Virtual Machine (VM) and if we want to migrate the Networker application to a new VM with a latest OS like RHEL 7.x, can someone share their experience and steps involved to accomplish this ?

In general the procedure is the same what I already mentioned:
- On the source VM (RH5)
- Create a new disk device
- Backup or clone the bootstrap to that media
- Transfer this directory to the new VM
- On the destination VM (RH7)
- Make sure it has the same name
- Install NW 8.2.4 in the same directory
- Define the disk device for your bootstrap media - do not label the media
- Recover the bootstrap or
If you know how to handle them you can just copy the NW databases.
- Recover the CFIs (not really necessary for a test scenario)
- Once you have your NW server up and running, you can upgrade to NW 9.x
What I mean with 'copy a VM' is nothing else but that. Because it is easier to test the procedure rather than to fix a broken system, you should use a clone for test/verification purposes. Of course you can also use snapshots but the changes may be huge.

If your current installation is also linux, it should be very easy.
Just make sure that the name and preferably the network address are the same.
Generally spoken, it is pretty similar to the standard DR procedure.
The detailed steps of course depend on your environment and setup.
And as you are running in a virtual environment, just copy the VMs to another VM server and test it.
- On the source VM
- Create a new disk device
- Backup or clone the bootstrap to that media
- Copy the VM to the destination
- On the destination VM
- Install NW in the same directory
- Define the disk device for your bootstrap media - do not label the media
- Recover the bootstrap
- Recover the CFIs
- Apply for new auth codes
If you know how to handle them you can just copy the NW databases.
The detailed steps of course depend on your environment and setup.

Thank for you response. Well the existing VM is on RHEL 5 and the new VM will be running on RHEL 7.x,
so what you are saying is copying the VM to desitnation will it work with the given OS version changes ?
So technically I think this is almost a DR like excersize as you mentioned and which I agree.
Also the current NW server version is 8.2.4.x and we have are considering to go with either of the options
- go with the latest of 8.2.4.x versions or
- go with NW 9.x versions which changes the whole picture.
I was thinking if we want to have NW 9.x on the new VM , how should we plan to smoothly transition over the existing configurations and run smoothly on the new VM with NW 9.x

Copying the VM is just a solution to exercise/verify the upgrade steps.
Copying the NW databases is a potential solution instead of running a NW DR process.
It is just a question how well you know the product.
Of course you must upgrade to 9.x at some point in time.
However, i would not do that right now.
And if you have the test environment ready you better learn this upgrade here.

I am not sure what you mean by Copy VM ?
Since our destination server is a brand new VM with RHEL 7.4 , what steps do you recommen to get the existing database and configurations migrated to the new server ?
Can you layout high level steps for me if you can in both the below scenarios ?
If the new server is going to have same version of NW
And
If the new server is going to have NW 9.2 version ?
