Do I have to use the new sim? Does it require pre-registering or is it all set to work in the phone?
Will my old sim (in S5 neo) work right off the bat in the new phone or does it require pre-registration.
If either Sim OK to use, is one recommended as a better option than the other?
If I don't have to use the new sim, can it be used in a Koodo prepaid phone?
If I use the new SIM now and keep the old, can I use the old sim again in my S8 with my current number if the new one breaks?
If I use the old sim now and keep the new sim handy, can the new one be activated at a later day on my same number if the old sim dies?
Thanks a lot to anyone who answers what is a lot of questions!

I think the S5 Neo is using a microSIM while the S8 is using a nanoSIM. If the old SIM didn't fit into the new S8, you need to switch SIM.
The S8 should come with an inactivated SIM in the box from Koodo. You would need to switch SIM in your selfserve following the instruction here https://www.koodomobile.com/help/koodo-sim-support
Once you switch to the new SIM, the old Micro SIM from the S5 would be deactivated, you can throw it away. Only one number with one SIM is allowed.
