Overview

To migrate Comala Document Management from a hosted instance, the Atlassian Confluence Cloud Migration Assistant (CCMA) can be used to transfer spaces, users, groups, and vendor app data.

You can assess and prepare your migration using the CCMA before migration. This includes an assessment of the apps you need in the cloud and a check on their availability and vendor support for the migration of the app data. In addition, the assistant helps you review your users and email domains.

Pre-requisites

Several tasks are detailed in the Migration to Confluence Cloud page. These must be undertaken before migration and include:

• Pre-requisite tasks such as installation of the latest app versions and reviewing app functionality in the cloud

• Pre-migration assessment of your current usage of workflows in your hosted instance

• Other pre-migration steps include removal of page restrictions, exporting page metadata, and consolidating your page workflows to include in the migration

For audit purposes, workflow event and activity history data are automatically preserved as a custom content file on pages with workflow activity from Comala Document Management Data Center v7.10.1. If you are using an earlier data center version of the app, you must manually run the Attach Activity utility prior to migration to preserve the full workflow event and activity history.

You should also have set up a destination Confluence Cloud site. You must have administrator permission in the cloud site to create and run a migration.
