At this writing, there are 30 questions returned for a search on
migration is:question. By my reckoning, these break down into three broad categories:
- 4 about using CiviCRM while moving from one CMS to another (what the documentation is usually describing when migrating is mentioned)
- 20 about moving a CiviCRM installation from one server to another (what the documentation generally calls moving)
- 6 about moving to CiviCRM from a different CMS platform, or from none (the processes of transitioning or adopting)
None of these terms is especially precise, but I would suggest we use transitioning to cover moving to or from CiviCRM from another CRM system or process. While the term is used in the book to refer to the process of moving to CiviCRM, rather than about the selection process, it has also been the title of the relevant CiviCon sessions, e.g. Introduction and transitioning to CiviCRM.
