Migration from 2.5.4 to 3.0.1 using vmotion with datastore relocation.

Migration from 2.5.4 to 3.0.1 using vmotion with datastore relocation.

Hello,

I am planing to migrate vms to ESX 3.0.1 using vmotion with datastore relocation.

Here I have some questions:


1- How many people have done this ? who had problems? who had not?


2- When migrating with vmotion, the vmdk file on the vmfs2 is deleted  after the migration is complete? or it remains on the vmfs2?


3- What if the vmotion fails?


I know the requirement and I also know that I may have problems since 2.5.4 is not supported for this type off "live" migration.


So any comments and help would be appreciated.


Regards


Thanks for your help


I'm not sure that it is possible to VMotion with datastore relocation from 2.54 to 3.0.1.

On these versions of ESX, I believe that you are going to have to  perform a cold migration (migrating a powered-off VM) if you want to  move the VM to a different datastore.  Even then, the different VMFS  versions (VMFS2/VMFS3) may cause some issues...Then again, I'm not  entirely sure from your description what you are trying to do. 

Can the ESX 3.0.1 host "see" the datastore connected to the ESX 2.5.4?   If not (and maybe if so) you may have to use WinSCP/FastSCP to move the  .vmdk files, then import them with vmkfstools or perhaps use VM  Converter.


I think you may want to use a tool called VMWare converter because you  won't be able to vmotion..  This will help you migrate your vms better  than using the vmkfstools -i format and copy.  Also, VMware is now at  ESX 3.0.2 Virtual Center 2.0.2.  Just an FYI

You also may want to read this site before you begine.

1- How many people have done this ? who had problems? who had not?

how many people --> I Dondt know Smiley Happy

problems --> some

2- When migrating with vmotion, the vmdk file on the vmfs2 is deleted
after the migration is complete? or it remains on the vmfs2?

You mean DMotion

I dondt use this.

on Vi3

create a new  VM, this creates the folder for the vm and than delete the  new created VMDK Files (you will deen only this folder and the config  files)

when the are able to see both SAN than

use vmkfstools -i /vmfs/sourcevmd.dsk  /vmfs/newsan/newvm/newvm.vmdk

with this option you are copying this vmdk when it fails, try again Smiley Happy

When the hosts are on different SAN than use fastscp from veeam

attach the vmdk files on your new VM and power on

migrate the VM Hardware, install  VM Tools and be happy.

In one of my project i used the original vmx file from ESX 2.x there are  some problems. its better when you create a new Vm on Vi3

i Hope this helps you

have a nice day

Well,

we tested it here without any problems, the only things is: Upgrade  using Vmotion and datastore relocation is not supported for the ESX  2.5.4 by VMware, that said, it is for 2.5.3.

So we made test on 2.5.4 to 3.0.1 without problems.

We also tested 2.5.4 to 2.5.3 to 3.0.1 since 2.5.3 to 3.0.1 live migration is supported by VMware this could be the way.

But I don't know why 2.5.4 is not on supported list and not on unsupported list on their official website: http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=8479101&sl...

1- Ho1- How many people have done this ? who had problems? who had not?

I did this and it worked so well 3 days after the migration was complete I was asked when I was going to start


2- When migrating with vmotion, the vmdk file on the vmfs2 is deleted  after the migration is complete? or it remains on the vmfs2?

the files get moved so yes deleted on the VMFS2 partition.  Vizioncore  has a migrator tool that will leave the VM intact during and after the  migration


3- What if the vmotion fails?

then the snapahot is applied and the systems keeps running until you can try again or do a cold migration
