Is it ok to replace a pump that has 2 inch in/out pipes with one that has 1-1/2 inch in/out pipes.

The new pump is 1.5hp variable speed, the old one is 1hp 1 speed.

Yes, it is ok to switch to a VS pump with 1.5" ports. If for some reason there was cavitation happening at the highest speed, you could reduce the RPM's and that would solve the issue.
