Hi Janko,
In short, you make such upgrade in three steps: .............
Thanks, looks like a plan.
What I don't know is how to export/import data in Squeak. With SIXX?
I usually use image segments but never tried between versions of Squeak. I would try with a non Cog image and then convert the image to Cog by once running it on Cog.
I'll give it a try. See some code I use for fairly complex objects below.
...... Ok, writing did not work, it stumbled over an instance of WebGridColumn even after I stopped the Webserver. But it wrote 1.3 MB before it stopped.
I' ll continue by first garbage collecting until there are no more subInstances of WebElement in the image like I do with my images and then try again. That will be tomorrow 5:30 :-)), I have private business now.
Cheers,
Herbert
