Do not migrate to a version of Squeak with a different Chronology
hierarchy. In general you would not want to migrate to a different
Squeak version at all.
General show stoppers for updates are class shape changes (Monticello
A general update path is somewhat like this:
- take a copy of your working image
- load Monticello-avi.279
- load or merge SqueakSource-lr.1013
- see if it works (go to a project and display the details of a version)
- if it works remove all the stuff that is specific to our
implementation (incomment saving of metadata, change the google
analytics account, enable SqueakMap realeases). Even better make them

There are quite a bit of improvements in all areas (speed, features,
fixes). Whether you need them desperately is a different question.

Do you have any examples?

Instabilities are caused by Squeak, not SqueakSource. So the answer is
no. You can try to make Seaside use IdentityKeyDictionary instead of

We do not store the metadata in a separate file anymore because that
takes too much time (and the Mac VM doesn't support forking). We are
unhappy with this solution but that's how it is for now.
For small installations saving metadata should be no problem. You will
have to incomment the respective methods.
In the Impara repository there is a Magma back-end. This is definitely
worth looking at.

Yes, as long as the shape of the repecitve classes (Monticello and
Chronology) has not changed. I would really just update the code instead
of setting up a new image.
