EZ Filer.... Changing sponsor from "XYZ CPA" to "Bob & Sue CPAs LLC"

XYZ CPA is a small CPA firm that employed Bob, Sue and Dick.  Bob and Sue are husband and wife, Dick is just the other partner.  No rank and file employees.  Dick decided to retire so XYZ is changing to Bob & Sue CPAs LLC.  B & S CPAs has its own EIN.  

Questions:

- I'm pretty sure that I don't need to terminate the old plan... I can just amend it to change the plan sponsor... correct?
- On the 5500-EZ, would I make the necessary changes and file?  (put in the new sponsor and EIN?)

Thanks

Correct. Updated info goes in 1 & 2 and old info in 4a and b.

Thanks!!!
