How to bulk shift product id in Magento 2?

Due to migration collision, I need to shift upward many product IDs.

Here is why :

If I use a delta migration from Magento 1 to Magento 2, new products in Magento 2, which have the same id than new products in Magento 1, are overwritten.

Is it safe to do such an id shift with SQL ?

Is there somewhere the full list of tables to update ?
