You may, or may not if the chain is long enough - I didn't when moving my 105 to 34x32 to 34x34 - in fact I have two wheel sets, one with a 32, the other a 34 and just swap between them. Just carefully select big chain ring to big chain ring and see if chain isn't too tight.

I would try it with the current chain, in place carefully to make sure there is enough length. if there is then cut your new chain to same length. if your current chain is maxxed out on the 32 (it should be quite apparent as if is as your RD will be pretty much pointing forwards on Big - big) then yes you will need to cut the new chain to a double link longer.

its good practice to start off a new cassette with a new chain, as using a worn chain with a new cassette will accelerate wear of the new cassette.

You may also need a longer cage rear derailleur?

To prevent the risk of damage, remove the split link, wrap the chain round the large-large, and then see if you can draw the ends close enough together to refit the link.

Large to large but NOT through the derailleur.

errr but then you need to add two links otherwise you will bust the derailleur.
But that method you part / mis quoted is only really relevant if you don't have an existing chain to measure to.

If you don't put it through the derailleur it defeats the point of doing it.

I'm talking about sizing the chain. Big to big plus two links.

There are charts on the internet.
