I tried using this procedure but it did not work. I used the backup from the old version 2.24.5 it produced a evolution-backup.tar.gz Sorry, it didn't impinge on my brain that you were using such an old version. So I killed all the programs and removed all the files in my user space and restarted evolution 3.4.3 on the new machine Did you try restarting Evolution without removing the files to see if it migrated the data to the new format? and downloaded files from my ISP provider. So far so good. But no files from before. Sometimes it is better to start from scratch and rebuild all the data - it depends on how many mail accounts you have, how your accounts are accessed and how complex your setup is. I'm going to have to do it at some point because I have crud in my Evo folders from much testing of various mail types, calendars, contacts and so on, and I have no idea which I can safely delete! So, look on the bright side P. ___ evolution-list mailing list evolution-list@gnome.org To change your list options or unsubscribe, visit ... https://mail.gnome.org/mailman/listinfo/evolution-list

It's in Fedora 15, so the easiest way of accessing Evo 3.0 is to install F15 on a virtual machine and use that to do the conversion - but see below. If I follow what you said below, Does this mean that I have to convert 2.24.5 data to 2.32 data and then to 3.4 or is it just one conversion? It's more likely to work properly if you go in small steps - there was a big change in data going to 2.32 and a similar big change going to 3.0. 3.4 introduced another change in the way the configuration data are held. Evo can probably cope with a single conversion, but it is more likely to get it wrong. The safest way is to go to 2.32 first, then 3.0 then 3.4. Andre was saying that it should be OK to miss out the 2.32 step and use 3.0 to convert that data from the 2.24 format. It is unlikely though that the Evolution backup files will work from 2.24 (the tar.gz file doesn't just contain data, it also contains settings that need to merged into gconf as part of the restore process, that's why you can't just untar the file and expect it to work). So you need to upgrade your (failing) machine first to Fedora15 - after taking a back up copy of your data! Then use that to create an Evolution backup file that can be imported into 3.4 on F17 Is there a utility that someone has that might do this job? Yes, it's built in to Evolution - I don't think there's an official stand alone utility to do it, although someone may have cobbled together a script for it.

Migration routines are written to convert data from the previous major release to the upcoming major release at the time of writing. So if I wrote a new routine today it would convert something from the way it's represented in 3.4 to the way it will be represented in 3.6, and that's about as much testing as it receives prior to release. The theory goes, as the routines execute chronological order, the data undergoes one or possibly multiple conversions but should end up in the currently supported representation. But as time passes, old migration routines may bit rot and silently break. Case in point: I believe the mbox-to-Maildir conversion itself still works in 3.4 but the detection for when the conversion needs to run is currently broken because it relies on some subtle aspect of the startup sequence that has changed since 3.0. In my experience, one of the better ways to do data conversion is to write an independent program to do it. Name it something like evolution-convert-3.2-3.4. After enough time, you would have a conversion program for each version and they could be run in order. They could also run without requiring a full working Gnome/Evolution environment so they could be used to convert offline data. On a backup server for example. -- Knowledge Is Power Power Corrupts Study Hard Be Evil signature.asc Description: This is a digitally signed message part ___ evolution-list mailing list evolution-list@gnome.org To change your list options or unsubscribe, visit ... https://mail.gnome.org/mailman/listinfo/evolution-list
Re: [Evolution] Data migration Evolution 2.24.5 to 3.4.3
I believe I have found a procedure to follow to do a migration/merge of data from a backup.tar.gz file from the old 2.24.5 version to the newer 3.4.3 version. The key piece of info that I needed was the format of the two different versions. Since I was only really using evolution as a mail system I could ignore most of the other files. I was only really interested in extracting the mail messages from the old version and saving them. Meanwhile I had started to use 3.4.3 so I had msgs that I did not want to lose so a full restore was out of the question. And the project became a merge of data from the old into the newer version. As I said before the prospect of upgrading the version on the dying machine was not available. I am in the process of writing a summary/procedure of what I did and how it works so that it can be done by those who suffer from the same problem I encountered.I will post those notes to this mailing list. I warn it is a bit long. But I hope it would help some. Thanks to those that responded and provided me the info needed to learn what I learned.
