Want to upgrade vB2>vB3, but have some concerns...

[mkdevo]

hello all,

i'm currently running vB 2.3.5 with vBPortal 2.3.0cr2. i want to make the upgrade to vB3 (and vBP3), but i have a few questions first, and i'm hoping someone can help out.

i'd rather not 'jump right in' to the upgrade. what i'm envisioning is a gradual process, but i don't know if it is possible:

i'd like to keep my current setup going, while i install and tweak vB3 and vBP3. so i guess what i'd like is for vB3 and vBP3 to be installed in a different directory, and just read from the same database as my vB2/vBP2.. is this possible? and if not, what can i do to set up vB3 for testing/tweaking before i go live with it? are there detailed instructions anywhere on how to do this?

hopefully i was able to get my point across ok. thanks in advance to anyone who can help.
