The ph will probably come down a decent bit with the driftwood, the alkalinity.. not sure, but a lot of the time, fish will adjust to the water.. you don't need to do it the other way around. The ph is a little high.. but hopefully the driftwood will take care of some of it. The rest can probably be adjusted to. Some people lower the water in their old tank if it's small enough and start adding some of the new water from the new tank, some put their fish and some old water in a bucket and do it that way, with an airstone for aeration. I'd look up a guide once you're satisfied that you've done all that you can do, and see if you can make the transfer easier for the fish.
