Problem reclaiming space in vmware

Recently had to move some vm's around on esxi 5.1 server.  Thin disk on server (S1) was out of control - expanding way too quickly.  Used VMware converter to move S1 to another host, converting to thick disk along the way.

Once S1 was up on temp host, had customer delete about 400GB of files (leaving about 450GB still on S1 c: drive).

Not enough space to put S1 back on original host as thick (was a 2TB c: drive only P2V) so I used VMware converter to move S1.  I ASSUMED only about 450GB would be transferred - wrong.  At about 600GB, I had to cancel the operation as my down time window expired and the converter still had MANY hours left.

Then used, for testing purposes only, Acronis to create a vmreplica, setting the job to convert to thin disk along the way.  Same thing so far - I've moved over 600GB of data.

What do I need to do to S1 before attempting another move?  I've read about sdelete and those types of tools; however, thought they were only needed for thin disk management.

My goal is to move S1 back to the original hardware (the datastore has 1.8TB available) as a thin-disk vm - with the expected consumption of less than 500GB of the 1.8TB.

How much actual space is i use  by the VM?

How much space do you have free on your datastore ?

What is the growth rate of this VM?

VMware Converter is the tool to use.

Windows reports around 450GB in use on c: (the only disk the vm has - provisioned at 2TB - the size of the original hardware disk the machine had before the p2v conversion 2 years ago)

The target hardware (also the hardware the vm was originally running on - we had to rebuild the RAID array) has 1.8TB of free space left.

I'm currently running an Acronis vm replication job to another datastore on the temp hardware - the job has "transmitted" over 930GB of data at this point and isn't done.

Also, I'm running my tests with Acronis as it can do them with the vm live.  vmconverter requires the source vm to be powered off - obviously, I'll do that for the "real" transfer anyway as this server hosts a live SQL database and we don't have vmotion or anything like that.

If Windows reports that only 450GB is "in use".

When you run VMware Converter, it will detect what the minimum size of the virtual disk can be?

What is this value ?

What size do you want the virtual disk to be ?

VMware Converter can convert VM Live!
