10 speed Di2 With 32 rear, best options.

bikes`n`guns

Looking to fit a 32 on the back for a visit to Gran Canaria.
What are my options ? apparently I can`t just change the cassette as the derailleur won`t work and I`ll trash the frame. Apparently.
Is there even a long reach Derailleur available for Di2 10 speed ?

My suggestion is to fit a 30 at the rear and a 33 inner ring up front. That's what I did and it worked just fine. Some have made a 32 work but I think it's a bit tight.

From USA but might be worth tying to get one from them.

Then you can keep the current RD
