The change from Familiar to Improved Familiar is left up to the GM but it should be a relatively painless transition.
When one of my players acquired an Arbiter Familiar I ran it as the Bat familiar she had was merged into the Arbiter. The memories became part of the Arbiter. No mechanical difference, just flavor.

Originally, this was posted in the Pathfinder Society board, and then it was moved here by a mod. So, I think the question is whether a witch can take an Improved Familiar feat for Pathfinder Society, and if so, does that mean that the witch must kill his/her familiar (technically, the witch class says nothing about a familiar being dismissed, only what happens if it is lost or killed), and if so, does the witch lose his entire spellbook?

The witch does not need to kill his/her familiar. For most purposes the witch uses the same rules as other classes with the familiar.
This uses the same rules as the wizard’s arcane bond class feature (see pages 78 and 82 of the Pathfinder RPG Core Rulebook), except as noted below.
The problem is that dismissing your familiar = dismissing the spellbook. Like I said, this is really GM territory. Unfortunately, some questions are intentionally left up to the GM but due to PFS rules that creates certain difficulties.
I would take it to the highest authority you can take it to. Start with your Venture Captain and then if an appeal is necessary proceed to the Paizo persons in charge of PFS.
Note: I am new to PFS myself and so take what I say with a grain (or pound) of salt. There should be some way to get PFS rulings from a PFS Paizo staff member.

Here's the problem.
If a familiar is lost or dies, it can be replaced 1 day later through a special ritual that costs 500 gp per witch level. The ritual takes 8 hours to complete. A new familiar begins knowing all of the 0-level spells plus two spells of every level the witch is able to cast. These are in addition to any bonus spells known by the familiar based on the witch's level and her patron (see patron spells).
So, the section of the Wizard's Familiar that deals with losing/replacing a Familiar is part of the text that's in the section that says it overrides the Wizard familiar text. And, as you can see, it only talks about the familiar being lost or dying. Actually, per this section, you have to pay to bring in an improved familiar, minimum of 3500gp (7 * 500gp, minimum level for imp familiar being 7 if I remember correctly).

MDT:
RAW: Since it does not cover dismissal then the earlier statement of following the arcane bond class feature applies. There was no exception to dismissal since it was not mentioned.
Note: I think this is an oversight and would require GM adjucation because dismissal still results in loss of the spellbook. There is certainly a problem here. Also, acquiring an improved familiar carries special problems for a Witch. Another situation requiring GM adjucation.
They really need to have a PFS rules section rather than bumping it to the general section. Generally: this would be solved by the GM. PFS has restrictions against such things.
