Merge a 403(b) into a 403(b)

[Guest PBJ]

This question will show you that I am very new to the area.

A small non-profit organization is going to become affiliated with a much larger non-profit organization. Currently both sponsor 403(b) plans. After the small non-profit becomes affiliated with the larger organization all of its employees will become employees of the larger organization. What should the small non-profit do with its 403(b) plan? Can it be merged into the larger organzation's plan or should it be terminated prior to the closing?

Any ideas?

Thank you!!
