AWS storage gateway migration

0

I need to migrate my AWS storage file gateway to a new one because the running one is being deprecated. Following this

https://docs.aws.amazon.com/storagegateway/latest/userguide/migrate-data.html#migrate-data-file-gateway

And not finding it clear

Current gateway runs on vmware, 4 disks.

By step 4 I have a powered off old vm and removed all 4 virtual disks from it.

deployed a new ova in step 5

Step 6 tells you to configure the network on the new vm, give it a static IP if necessary. Then Step 7 is turn it on. Not sure how you can configure an IP before turning it on, but that's fine it still makes sense.

Step 8 is to attach the old disks to the new vm. Question - do I remove the disk that's already there on this new vm? Or attached all 4 old disks so I now have 5 attached? Why am I told to attach them with the vm running?

Step 9 is go to a url the example given is

http://198.51.100.123/migrate?gatewayId=sgw-12345678

The IP used must be my new VM ip (can be the same as the old one) and the gatewayid is the exisiting gateway ID?

Now step 11 is stop the new vm

Step 12 is to detach the old gateway's root disk. So my new vm is back to 4 disks? Is that right?

I'm a little confused.

Anyone been able to do this procedure?

  • Thanks for helping. Successfully migrated now.

The instructions provided in this page assumes that you would like to keep the data in the Cache disks by detaching cache disks from old gateway and attaching them to the new gateway.

do I remove the disk that's already there on this new vm? Or attached all 4 old disks so I now have 5 attached? Why am I told to attach them with the vm running?

In your case, you will have 5 disks attached. The reason for attaching them to the running vm is to allow migration in Step 9 to copy the data from the old root disk to the root disk of the new gateway vm.

The IP used must be my new VM ip (can be the same as the old one) and the gatewayid is the exisiting gateway ID?

Yes, it can be the same IP address as the old one.

Step 12 is to detach the old gateway's root disk. So my new vm is back to 4 disks? Is that right?

Yes, correct. At the end of the process, your new gateway will have its own root disk and 3 cache disks from the old gateway.
