Study pp.8-1 through 8-3 of the Public Health Grants Policy Statement;
these cover changes in PI and changes in grantee organization.

The award really is made to the grantee institution, not to the
PI; this is not just "technical," whatever that may mean.  The award
notice identifies the institution as the awardee, and the words
mean exactly what they say.
