Hi I don't know if this was reported. Apparently there is a problem when migrating a large number of instances, I have aprox. 270,000 instances from which I simply pulled up an ivar in their class to a higher superclass, and a PrimitiveFailed raised. It can be reproduced by installing Territorial in Pharo 5.0 with Spur VM 5.0 from 4 May 2016 in Windows 8.1 (this is the standard image installed using wget command line in msys). Gofer it smalltalkhubUser: 'hernan' project: 'Territorial'; configuration; loadDevelopment. TCityOrganization addOpenGeoCode Then manually install Territorial-HernanMoralesDurand.163 from Monticello. Backwards (installing .163, populating, then .166) also reproduces the issue. Is there a fix for this? --- The full stack --- Array(Object)>>primitiveFailed: Array(Object)>>primitiveFailed Array>>elementsForwardIdentityTo: TerritorialCity class(ClassDescription)>>updateInstances:from:isMeta: TerritorialCity class(ClassDescription)>>updateInstancesFrom: PharoClassInstaller>>updateClass:to: [ 1 to: old size do: [ :index | self updateClass: (old at: index) to: (new at: index) ]. old elementsForwardIdentityTo: new.
