Migrating the tracked data from Server/DC to the Cloud requires the following steps:
Exporting the existing views and viewer data from Server/DC
Importing the views and viewer data into the Cloud instance
Mappings of page ids and user key. The page ids and user keys need to be changed from Server/DC data into Cloud data.
bitvoodoo implemented an automated migration path that is part of Atlassian's Migration Assistant. It is therefore not necessary to manually export and import the data. The automated process is explained in this document.
Restrictions of Viewtracker Data Migration
For technical reasons, it is not possible to import the Viewtracker metrics “Edits” and “Creates”. These metrics will sadly be lost when migrating to Cloud.
A maximum of 2 million Viewtracker views can be migrated in one go. If you have accumulated more than 2 million views, you need to split the migration into various batches.
