Yes, usually. That depends a bit on the Products you have installed. When 
you remove a product, all its instances will become broken (your zodb might 
contain such old instances even if unused). Or, if the product does some 
not-so-portable things like storing a full path to an external file as an 
attribute (there are some examples...) you'll have some problems if you 
install into another directory. But in general, if no such odd things 
happen, it's just "plug and play".
