In the EnterprisePharo Book there is a chapter "Fuel Format Migration". There the format migration form Fuel version 1.7 to 1.9 is shown. I ask me if there is a similar possibility for the migration between Fuel in Pharo 4 and 6.

Your suggestion is correct. I correct the expression to

(FLMaterializer materializeFromFileNamed: aFileRefence fullName)

Now I get another exception.

KeyNotFound: key #'ositive8SmallIntegerClusterJ 4�� 1��� ��+ ���( %? "< 9 �� 6P M ��0 d *��D ''x ! �� 8' not found in SystemDictionary

I think this is a compatibility problem between different Fuel versions.

Hi,

If you use Fuel to serialize objects with Pharo 4, then you can only materialize them with a Fuel from Pharo 4. Other versions of Fuel will not be able to read them.
