Is the decision to use SNI or IP based SSL made during cert purchase or cert installation?

It's time to renew an SSL cert - but the website will soon be moving from a dedicated machine with a fixed IP to a cloud based host behind a load balancer.

When I renew or re-purchase my ssl cert do I make the decision about whether it should be an SNI / IP based SSL Cert at the point of purchase - or is a cert a cert and it's all about where and how it's installed?

I'm hoping the renewed cert can continue to be IP based for now, and in a few months when the website (and it's domain ofc) moves to the cloud I can re-use the cert in 'SNI mode'
