Zone migration ACS

Hello,

 

    I have a question, I have 2 cloudstack management console, is there a
way to migrate from A to B ? I like to use just one management console this
is why I ask this.

 

   Example :

 

        Cloudstack Management - zone A

 
---------------------------->  CloudStack Management zone A and B

        CloudStack manamenegt - zone B     

 

 

Thank you,

Cristian

Hi Dag,

  Thank you very much for clarification, I thought is a way for migration like this, but now I see the logic.

Cristian

Hi Christian,

I guess what you mean is you have two different CloudStack environments – A and B – and you want to collapse these into one single CloudStack environment?

Whilst I wouldn’t say it’s impossible it would certainly be a fairly huge challenge. Both your DB backends will be using the same database entry IDs for e.g. VM instances, volumes, networks, etc. To migrate one CloudStack instance into another you would have to change all DB entriers for the imported zone, then update all database internal references for the same. This would be a huge task and most likely very error prone, i.e. I would advise against trying it.

If you however could export all VMs from CloudStack B and import them into CloudStack A then this could work. You could even do a slow migration where you slowly evacuate all VMs from one hypervisor host, migrate the VMs to destination CloudStack, then rebuild the host and add it to destination CloudStack A – then rinse and repeat. This way the destination CloudStack instance would deal with all internal DB consistency itself as part of the template/disk imports and subsequent VM startups.
