🙃🙃🙃🙃🙃Upgrade from Njoi to Ultra Box should be okay, since it's just swapping STB to the Ultra Box, as well as installing new DCSS LNB on your satellite dish. So for this part, don't worry.
However, another part that maybe you might wanna worry is, I noticed some customers complaints that they just their Ultra Box installed, and the technician left their house before their smart card is being activated.
Technician told them that the Astro smart card will be activated within 24 hours, so "don't worry".
But in some cases, more than 24 hrs has passed (some even 3+ days), and customer still unable to watch Astro, as it still shows that 'please insert correct smart card (CA 14)' message, because the card is not yet activated by Astro.
According to them, they could only watch TV1 and radio channels, and nothing else.
When contact Astro, they say another agent will get back to you, and at the end, nothing happens.
So it's like this agent throw to another agent, then throw to another agent, throw here and there, at the end you sit down and wait lo.
So, you want fast? I give you fast.
Perhaps, it is advised that you should be mentally prepared that you might not able to watch Astro for a few days.
Maybe because they wanna "mass activate" all the accounts, instead of technician activate the accounts one by one per technical visit like that, which is maybe kinda time consuming to them.
Even if they go for the "mass activate" method, you wouldn't know whether they would 'accidentally' skipped yours or not.
Like I said, you want fast, I give you fast.
Or maybe, it's just an isolated case... Maybe it wouldn't happen to you, I dunno
