Will we ever be forced onto 2.0?

[Treacle100]

I have a highly customised shopify 1.0  - is it worth me going through the pain of converting to 2.0 or will 1.0 always work within the shopify structure.

eg. will the checkout etc always work for 1.0 themes or do we think that this will be removed at some point down the line and therefore better to go through the pain and convert now?

 you will if you  if  update your theme  to the latest version  

if you do not update, you will stay the same

Thanks but what I mean is will we ever be forced to change to 2.0.....or am I safe staying on 1.0 .....will there come a time when the site stops working as shopify decommission old checkouts etc if i remain on a 1.0 theme?
