More than one instance Oracle XE

Question

I have a vm running Windows 7, which I use for testing web applications in IE8 and IE9. Also, I use this vm to run Oracle XE.

I have a java system that will have some changes. These changes will modify the database, but I need to keep the old version of the system and the old database structure. I was thinking of using more than one instance of Oracle and apply the new version of it.

Problems:

1. An vm Windows 7 has an average 30gb and I only have 17GB free.
2. I'm using Oracle XE, so I can't have more than one instance.

Any good idea?

"An vm Windows 7 has an average 30gb and I only have 17GB free."

It's 2012, almost 2013. We can buy 32GB thumb drives for a pittance. If you really can't get hold of a server with more disk space you'll just have to externalize. The performance might suck a bit, but presumably you're just interested in functional testing.
