After importing the product entity into a new organization I noticed something weird.

In my development environment I deleted all the options of the product type options set and created 2 new ones.

I exported this entity (unmanaged) and imported this in another clean organization.

The end result was that the product type had 6 options. The 4 default options and my 2 new once.

Which is kind of strange because I thought options get replaced when you import a solution. In this case the options merged.

I tried to reimport the same solution in the same organization again. Now I had only 2 options sets left.

So importing the same solution 2 times gives you different options sets. So again something extra to check when importing/exporting organizations…
