Porting a number to a new provider and requesting a new Koodo number

Hello

I have a Koodo number that I have been using for my business. My business has grown to the point that I now need a business phone line and a personal line. What I want to do is port my koodo line to the new business provider, and be assigned a new line. I have a few questions

1. Should i request a new phone number from Koodo first, then port the old number to the new provider?
2. Do i need a new sim card to use that new number
3. How long does it take on avg to get a new sim

Anything else to consider?

Thanks

Rebecca
