OK, I've got the Zinstall XP7 software.
I tested it on
2 setups:
1) Upgraded a HP DV7800 Desktop from XP Pro 32bit to Windows 7 Ultimate 64bit. The PC had a 500GB HDD, about 230GB used space. I've done a "custom install" of 7, and then ran the Zinstall software. It took about 2 hours to complete the "Zinstallation".
Created the XP VM successfully, can switch between the XP and 7 modes instantly.
All apps are perfectly operational! (except the HP utils)
Can access files. Can copy and paste with "ctrl+C / ctrl+V" between XP and 7.
Seems that copying with file access is faster than with the shortcut, otherwise both are fine.
Can access Internet from the XP VM.
2) Migrated a Toshiba Tecra S2 laptop to an Acer Aspire 5735 laptop. Tecra had 40GB used.
On first try couldn't activate the software, since it needed Internet access to activate. They did have an option to do an "website-based activation", but didn't want to bother. So I connected both laptops to a router, and it worked out OK from there.
Migration was done over the net, took about half an hour (!). Note that both laptops had Gigabit network adapters - 100MBit models can't possibly reach THAT kind of transfer speed.
Once complete, the result was similar to the "in-place" migration.
Final remarks:
Overall -
very positive impression. Will have to see how it goes for a couple of days, monitor stability / system resources.
The "dual-channel" environment works very smoothly right now. I have not yet provided such a migration to a client, but for the last couple of hours I did not have any glitches. Even the laptop runs without hiccups (it does have 3GB of RAM, though).
If everything works out OK for a couple more days, I will definitely start offering this.
Zinstall XP7 seems to be a pretty new product (was probably released Oct 22 with Win7), but it sure does what it promises. I also start seeing some press about it -
like InfoWorld here - but we've been there before they were famous!
