I have magento 1 and a message popped to change to magento 2. I purchased two extensions for the old platform now i have to purchase them again for the 2 version?
while the code migration script is available:
but I think that for the sake of your business you should buy the same extensions for Magento 2.
Development and maintenance costs will be even much more. Count yourself - proper working shop is more important, the final profit will cover all purchases of updates.
