Import a pharo 6 image in pharo 7

I have a prototype of an application with image persistence made in pharo 6.1.
I wanted to export (upgrade) the data (database, objects, collections) of the image and code to Pharo 7.
It is possible to perform that operation.
Thanks in advance

Hi,

You could try to serialise/deserialise your data with either STON (textual) or FUEL (binary).

'mydata.ston' asFileReference writeStreamDo: [ :out | (STON writer on: out) nextPut: objectGraph ].

'mydata.ston' asFileReference readStreamDo: [ :in | (STON reader on: in) next ].

If you have more questions, just ask.

If you use Fuel, this may help:

Thanks Sean and Sven

I'm going to investigate Ston and Fuel to do it.
I also thought about passing the data to CouchDB (document database) and then accessing from a clean Pharo 7 with Seaside and Bootstrap.
How do you think the status of the drivers for Pharo for CouchDB is currently. I used it for an application for production. Also Mongo but he changed his license.
Thanks in advance

I wouldn’t recommend Mongo for this use because it doesn’t automagically resolve cycles, so you would have to do a lot of work in order to serialize the data. I agree with the previous suggestions and use Fuel or STON.

Alejandro

+1. Either of these methods is pretty much a one-liner. The main hiccup with
Fuel is installing the same Fuel version in both the source and target
images.

Re: Import a pharo 6 image in pharo 7

Thank you for your answers
I will try STON first.

After passing the data from pharo 6 image to pharo 7, I also want to move it to Document Database.

This process is not vital at the moment, I can do it in steps.

For this reason, I asked about Mongo and CouchDB.
