Does anyone have experience transferring from UniFi to Astro Fiber with different account holders?

UniFi: My sister's name
Astro account: My name

Now we intend to apply Astro Fiber and I assume it will be a transfer since it is in the same address? Or how will it work?
Add on: Coincidentally, someone from Astro Fiber called me and confirmed it works even different owners' name.

Just go to My Astro app and play around with the Astro Fiber bundle plan. I didn’t even submit it on the app and someone from Astro called me and asked if I was interested, I said yes and he helped me to submit everything. Then got the transfer ID and UniFi called to counter offer.
