ESX VM migration and extending disk drives

So I'm trying to do a vm host & storage migration to another datastore and host. I also want to extend the vm drives and make them bigger. But for the life of me I can't figure out how to do this either through vmconverter 4.3 or through a straight migration. What i do know is that someone did do it and they did it as part of the migration process. This person isn't around right now and I need to know how to do this.

I was going to do a cold migration but with a cold migration the advance options does not allow me to change the disk size at all. Do i need to run it live in order to have that option?
cold migration is not the same as Converter.  migration only changes the host or datastore, so you can migrate the VM and then edit the settings of the VM to increase the disk size...

I was going to convert the vm cold over to another host and store

Hi

@prak_seafarer this only increase on VMware side, not on the VM guest OS side. For this need to follow what coolsport00 as already added.

Only for Windows 2008, Windows 7 or Vista, we can expand the disk without the need of Diskpart or any 3rd party partition tools

Yes, diskpart can be used, but *ONLY* if the volume is a non-system volume. BTW...that is the same link I posted earlier.

Hi

@prak_seafarer in Windows or Linux guest, using or not 3rd party partition tools, or Diskpart, you always need to do this in the VM Gues OS side.

So edit VM settings with the VM power off or on, is not enough to expand a disk on the VM Guest OS.

Looks like I could extend the volume by using the Vmmware converter. All i had to was to edit the size of the existing disk up to the size I wanted and it worked. Even on the C:\

Hi

Yes like I said is show in my article(not related with this, but have a step that can do this).

But still I think is easier to use a 3rd party partition tools, or Diskpart(if not a system disk).

But glade that you manage to do this.

Several choices for you really "iamuser". It's really up to you to decide what's easiest and most non-obtrusive for your org. Glad it's all worked out...

well with the vmconverter I don't have to do any of the Diskpart or any 3rd party paritioning tools. It's all done at the time of migration. I know it could be done I just didn't know where in the converter I could do it. I had to dig and experiment some more

I'm was very surprised  that no one



...surprised that no one suggested Converter? Well, I we normally we do, but just forgot, or got caught up in what was being discussed already. And honestly, doing it the other ways mentioned is quicker. It can be done in a few minutes as opposed to 1/2 hr or so (depending on VM virtual disk size). As long as you're up and going...that's what counts. :)

Thanks for all the comments, the reason why I didn't want to use the gpart live cd is because it adds an extra step after my p2v. With the converter I can set it and let it all go as one process
