Redmine to Azure DevOps Migration
This repo has a couple of scripts that can help you to migrate from redmine to Azure DevOps. It is not a fire and forgot kind of script but acts as a starting point for your own migration.
Issues
The script migrate.py will migrate your Redmine issues to Azure DevOps work items.
To use it you have to:
- install the dependencies in
requirements.txt - adjust the constants at the top of the script (redmine url, tokens, etc)
- adjust the filter of redmine issue at the top of main()
After that you can try it. I highly recommend to first try it on a test project.
It does not migrate everything perfectly. What works:
- Attachment are migrated (it will not work with files > 130MB)
- Parent/child relations are migrated
- A link to the original redmine issue is added to each work item
- Comments are migrated
- References to issues are replaced with a reference to the new work item id. A relation to the mentioned work item is added but the link itself will not work.
- The 'state' of a redmine issue is mapped to a state Azure DevOps with the dict 'state_map'. The default is 'To Do'.
Caveats:
- Comments always have the authorship of the Azure token owner (the API doesn't allow you to change it).
- Tracker information is not used in Azure. We add it in a table at the bottom of the work item.
- Redmine markdown is not 100% standard compliant (or at least not with the python markdown module). You may lose a bit of the formatting
The script will also dump a json file with the mapping between redmine issue ids and azure work item ids.
wiki
The script wiki.py will 'download' all the wiki pages and put them in a directory
structure. This can then be added to the git repo of a Azure DevOps wiki. To find
the git repo for a wiki, read this.
change issue numbers
With the script migrate-wiki.py you can change the issue references in the wikipages to the
'new' work item id in Azure DevOps. You need to use the json file dumped by the issue migration
script. Example:
find -name '*.md' -print0 | xargs -L1 -0 python3 migrate-wiki.py issue-mapping.json
