How to Migrate OpenManage Enterprise From 3.10.x to 4.0

This video will demonstrate the how to migrate OpenManage Enterprise from 3.10.x to 4.0.

Hello, my name is Ted. I'm a Principal Engineer in the Systems Management space at Dell Technologies. This video is for migration between OpenManage Enterprise 3.10 to OpenManage Enterprise 4.0. The purpose of this is to preserve all your device data, application configuration, and plug-in data from your previous Appliance, version 3.10. Prerequisites for migration, you need to be logged in as the local administrator, the admin account, on OpenManage Enterprise.

Need to make sure there is enough free space on the OpenManage Enterprise 3.10 Appliance before running the migration operation. Make sure that all services are running, and the network connection is stable between OpenManage Enterprise 3.10 and the new OpenManage Enterprise 4.

Make sure that all installed plugins are enabled on your OpenManage Enterprise 3.10 Appliance. Make sure that the OpenManage Enterprise 4 appliance that you have stood up to receive the migration data is online and able to reach the OME online catalog. Make sure that debug mode and Field Service Debug mode are disabled on the appliance.

If you are leveraging a web certificate signed by your Certificate Authority you need to make sure that you have the certificate chain available as both certificate chains will need to be uploaded to the 3.10 and 4 Appliance from the same Root CA. Certificate chain does have to contain all the certificates in the chain from the OME certificate, to the root CA. So, to begin the backup and migration process here, we're going to log into OpenManage Enterprise 3.10, then we're going to go to ‘Backup/Restore’ and choose ‘Migrate’.

We are going to be migrating out from this Appliance so we're going to proceed currently with the self-signed certificate, and I'm going to provide connection details for the new OpenManage Enterprise 4 appliance. Validating the certificate will prompt me if I want to trust the certificate for the other Appliance. I'm going to choose ‘Yes’, which will restart the web services on OpenManage Enterprise 3, so we'll take a minute for those to be available. I'm going to move over to OpenManage Enterprise 4 Appliance and begin the trust process here.

So here I'm just going to go with the ‘Migrate from a 3.0x appliance’ which will take me right to the migration screen. Since I'll be using the self-signed certificate I'm going to proceed with that, and then provide the console details for my original OpenManage Enterprise 3.10 Appliance. This will give me a popup showing me the certificate details for the OpenManage Enterprise 3.10 Appliance.

I'm going to click ‘Yes’ which will restart the web server on the OpenManage Enterprise 4 Appliance. Back to OpenManage Enterprise 3, we do have the certificate trusted now. I'm going to provide again the contact details for the OpenManage Enterprise 4 Appliance. Validate the certificate is trusted and apply these settings. Now, this here is telling us that once we provide this encryption password that it's going to start the process of putting this into a maintenance state.

We can't really continue to perform the remaining steps of the migration until this Appliance is fully in a maintenance state. So what I'm going to do here is provide the encryption password that I'm going to use. If you click on the information, or hover over the information, it will show you the requirements for this password. Apply those settings, and now it says to log into the target console and perform the migrate in options.

So we're going to go back over to OpenManage Enterprise 4 and perform these operations. I'm going to separate these out so it'll be easier to see, this way we have a side by-side view between OpenManage Enterprise 3 and OpenManage Enterprise 4. So, I'm going to provide my connection settings, trust the source appliance certificate - which is successful - and then validate my connection to OpenManage Enterprise 3.10 Appliance.

Here we're presented with the ‘Import Readiness Report’. This is going to give us an idea of what the state is for each one of these components, plugins for OpenManage Enterprise 3.10 and what the version is for the destination as well as the installed status. So here we can see that the plugins are available to install, if you don't have internet connectivity at the point that you complete step two this will this process will hang and will not continue until we can get to the internet and reach the OpenManage Enterprise catalog from the OpenManage Enterprise 4 Appliance.

Currently we're waiting for the OpenManage Enterprise 3 Appliance to be put into the maintenance state. If you see here we have the banner telling us that it is a ‘Maintenance Pending’ state and we can check for more details on the job to verify the status of that. As you can see after two minutes we're 15% complete, so this process will take some time. So here you can see after about four and a half minutes my Appliance is now in the ‘Maintenance’ state.

Now we can continue our migration process here as we are allowed to enter the encryption passphrase. It's the same password that we provided originally, and then we can ‘Import’. We do have to accept the license agreement for the plugins that will be installed. Now this process will take some time, plugins are installed, the data is streamed across the network, database is stood up, all the devices and everything will be entered into OpenManage Enterprise 4 and then it will run the original discovery jobs.

So these these jobs do take longer because it has to run them twice on the OpenManage Enterprise 4 Appliance, so that process can take some time. If you do run into any problems during the migration process there is an ‘Abort Migration’ option here, which will abort the migration that is in progress. We're still waiting on one more reboot from OpenManage Enterprise 4 to finalize the installation of everything.

Here we can see that the appliance has moved to a decommission state and after several reboots our new OpenManage 4 appliance is up and ready to be logged into. Here we can see that the last import job was successful, we can view those logs. I’m going to make this full screen so it's easier to see, and here you can see from the logs that everything was completed. That concludes my video for migration between OpenManage Enterprise 3.10 and OpenManage Enterprise 4.

Thank you so much for watching, have a great day.
