VxRail move to new cluster

Are there any work arounds to migrate a VxRail from one external vCenter to another?  There are articles on how it can be done with a generic vsan cluster, but all documentation i've seen for VxRail states the VxRail needs a factory reset.  With new nodes requiring VxRail 4.5 (which requires vCenter 6.5) I can only assume others are in the same boat as not being at vCenter 6.5 yet in large environments.

The Procedure is in Solve. If you don't have access to it, please work with support.

Hi Garret,

Use the procedure to migrate from internal to external vCenter. Officialy not supported, but it works.

Could you post that procedure? 

Thank you.

Hi Garret

A couple of things to just be aware of on this as we looked into the external vCenter for our clusters.

  • If you use an external vcenter you cannot perform a straight for "click" update using the VxRAIL manager.
  • You get vCenter licensing with VxRAIL for an internal vCenter not an external so you have to buy it and maintain it.
  • Generating log bundles doesnt work correctly.

With the procedure EMC_Troy says its not supported unless you get EMC to do it so be aware of that. So in theory the best way is to rebuild the cluster as that is supported.

Hope that helps.

Thanks again Troy.  I can't see that Migration section so it looks like EMC and Partners only.  I'll work on getting that.

Hi Jon,

A few points to what you mentioned:

  • If you use an external vcenter you cannot perform a straight for "click" update using the VxRAIL manager. - We've upgraded all of ours this way successfully.  Some had hitches in a few since we've had them since very early versions but recent versions were smooth.
  • You get vCenter licensing with VxRAIL for an internal vCenter not an external so you have to buy it and maintain it. - True but we have clusters all over the world.  vCenters all over the world would be a management nightmare.
  • Generating log bundles doesn't work correctly - We've worked through issues so i'm not sure what you're referring to but I will say many of our log gathering was manual.
  • Rebuilding the cluster just isn't an option after it has data and deployed. 

For Dell EMC VxRAIL to stay relevant the ability to migrate to new vCenters in a supported way is a must.

IMO the internal vcenter has very little use case for us.

Thanks,

Garret

Hello
The procedure aren't available anymore.
Do you have a link to get it ?

Hi Garret, I found your old post here about moving vxrail clusters.  I am about to undertake the same process, moving a vxrail cluster from an external vcenter to another external vcenter.  Do you have any tips or docs you can share other than the solve procudure?

 

Feel free to email me directly 

Thanks for anything,
