Agree with the Captain.... it is always best to do a clean install from scratch, but more time. I have been able to use Acronis to convert from a good HDD build to a SSD build multiple times, but my instincts still are always to do a clean install from the HP/MS DVD.
I think I may understand what you are up against. You have one HDD with your current OS/programs on it and you want to create an image of that and clone it onto your new SSD. With Acronis you can do that on another workstation and when you are done you can put that cloned SSD into your single slot and boot from it. You boot from the Acronis CD and target the drive you want to capture the image from, and point to the drive you want to capture the image to.
Again, you can capture the image from your current boot HDD using a workstation that is not your Z1, and you can use a workstation that is not your Z1 to then clone from that image to a SSD and then later transfer that SSD into your Z1 and boot from it once installed. We could accomplish that in about 20 minutes here... bring the beer.
Or, if you have the image captured on a drive you can transfer that image to a thumb drive, and then you could put your blank SSD into your Z1 workstatin, plug in the thumb drive into the Z1 (with the single image file on it), boot the Z1 from the Acronis CD, target to the thumb drive for your image source, and target to the blank SSD to clone onto. Then remove the CD and boot from the SSD.
I generally use an eSATA drive for these projects.... it is on the fast SATA bus, easy to target to for capturing an image to, and easy to target to for cloning that image onto an internal blank drive. For our HP workstations it is easy to just plug in an adapter to have one of the SATA internal ports be dedicated to an eSATA port on the backplane. If you only have one internal SATA port then you can't do that. I use this approach on all xw6400, xw6600 and Z620 workstations.
There even is an Acronis Cloud you can capture your image to, and clone off that, but I have never used that.
