I moved from Unifi by requesting port transfer, here's what likely going to happen to you:
1. Sign up for Digi Fibre on the coverage website. They'll contact you within a week; during that phone call/e-mail, you let them know you want to port over from Unifi/Maxis. They advised me to just go to TMPoint request for port transfer.
2. For me, I went to TMPoint, requested for port transfer. Your case may differ, you probably will have to go from Maxis Store to TMPoint. Prepare to pay your final bills. Wait for Digi to call you for installation date. During this time, you will still have internet/phone/TV from Maxis Fibre.
3. The installer comes in and replaces only your router and keeps the old modem.

It's much better to keep your Maxis and request port transfer because you will lose internet (and time) if you decide to terminate contract, wait for TM for your port to be released and then go to Digi.

TL;DR: Go to Digi's website at fibre coverage page, register your details, they'll call you and you tell them you want to move from Maxis to Digi. Good luck, bud.

I haven't had internet for 2 days and Digi told me the fibre team told me to wait 1 to 3 days for them to get to me. Seriously?

I am very sorry for the late reply. Anyway, when you are talking to the customer service or the "fibre team", be very firm and ask for compensation for loss of use. They will say oh, "we won't charge you for the days you've lost internet". Well, I lost 6 days worth of internet, and my next bill was the same 95.40. So I sent an enquiry on mydigi app, I was pretty rude but I reminded them I was not supposed to be charged for the days I lost internet. A few days later, my bill in the app went from 95.40 to 71.something.

Don't pay in full EVER if you lose internet. Make them earn it for wasting your time.

Did your bill also get "upgraded" too? I was not informed of a speed or a bill increase and CelcomDigi gave it to me. My 50mbps become 100mbps and my bill went from RM95 to RM104 after taxes. What free upgrade did any of you get? I was coerced into this without any notice or my approval.
I am out, I am going to try to get back to Unifi albeit with another 2-year-contract.
