MagmaUpgrader missing methods?

[Hernán Morales Durand]

I've installed Magma in Pharo 1.3 OneClick following instructions here:
http://wiki.squeak.org/squeak/2657, i.e. applied patch
Pharo-1.3-patches-for-Magma.cs.gz<http://wiki.squeak.org/squeak/uploads/2657/Pharo-1.3-patches-for-Magma.cs.gz>and
doIt to the script
Pharo1.3-load-magma1.st<http://wiki.squeak.org/squeak/uploads/2657/Pharo1.3-load-magma1.st>

I tried to upgrade my databases from version 12 to 16, but there is no
MagmaUpdater #compressTo: or #source: methods as described in a previous
mail in this list. Instead I've found this way:

( MagmaUpgrader location:
'd:\Smalltalk\Projects\Browsers\MagmaBrowser\MBTest7\') upgrade

but it is failing again

MagmaUpgrader(Object)>>subclassResponsibility
    Receiver: a MagmaUpgrader
    Arguments and temporary variables:

    Receiver's instance variables:
        location:     'd:\Smalltalk\Projects\Browsers\MagmaBrowser\MBTest7\'
        definition:     nil
        session:     nil

MagmaUpgrader>>legacyVersion
    Receiver: a MagmaUpgrader
    Arguments and temporary variables:

...

do I need to install an additional package or there is an alternative way
to upgrade?
Cheers,

Hernán
