Select a migration task from the ‘Migration Tasks’ panel on the left. Click the “Discover” button in the ‘Discovery’ area and the select "New Discovery" from the dialog box.
Migration Accelerator will start discovering items from the source system and record their status in the staging database repository.
The pre-migration check feature identifies any potential issues with the discovered items that might affect your migration. You can start the pre-migration check by selecting the "Check" button from the Content Analytics section of the Execution tab.
This will then present you with a screen to configure the check parameters, this allows you to modify the rules if you have any custom requirements.
Once you're happy with the settings you can click the "Run" button to begin the Pre-Migration Check.
The results of the check can be seen in the Power BI report.
After successful discovery of all items present in the source system, click the "Process" button in the ‘Processing area’ in order to start the content migration. This will launch the processing parameters popup window in which you can configure the processing parameters.
The available parameters cover:
- Process to stage –The migration goes through below processing stages, so one has to select appropriate target processing stage from below list:
- Capture Metadata – This stage captures metadata of all the items from source system.
- Classify – This stage performs content classification of all items based on content type mapping defined in migration task settings. This stage may retrieve content if required in order to perform content classification.
- Filter – This stage applies item filter rule in order to skip certain items in migration.
- Extract – This stage performs an extract operation on source metadata if any.
- Transform – This stage mainly transforms source metadata to target metadata by executing different metadata mapping rules. This stage may retrieve content if required in order to perform transformation.
- Load – This stage retrieves content if not obtained in earlier stages and performs upload of content and metadata on target system.
- Type of items to process
Here you can find the Process Errors flag which tells the application to reprocess any items that had failed previously.
- Throttling parameters
This section allows you to throttle the application either performance or item wise.
- Maximum number of items to process – Allows you to select the maximum number of items that will be processed in the processing run.
- Maximum number of threads – Allows you to select the maximum number of threads to use during migration, in simple terms this is the number of concurrent item loads that can occur at a time. Increasing the thread count corresponds with an increase in through-put but can lead to a higher load on the migration and target systems.
Once all processing parameters have been selected click the “OK” button to start the migration or click the “Cancel” button to cancel the processing.
Upon clicking the “OK” button the application will start processing each item based on the mapping rules that you have defined. The progress of the migration will be displayed in the processing dialog screen as shown below.
The "Successful items" count shows the number of items that have successfully processed up to the target stage in the current processing run.
The "Errors" count shows the number of items that have failed in the current processing run.
If you have enabled package processing you will see the number of items successfully packaged on the left hand side, once these items have loaded onto the target and been verified the success count will go up appropriately.
Proventeq Migration Accelerator supports one-way synchronization from Documentum to Office365 /SharePoint.
If source contents are changed after particular task discovered and/or processed, then user needs to re-discover the same task to synchronize the updated items on the source system. Then user need to do pre-migration checks followed by processing and post processing on newly added or modified items.
In Synchronization or Delta Processing, using packaging, Original document which is modified will be deleted from target in the first processing attempt and then in subsequent processing attempt, they will be migrated.
The ‘Reset’ functionality is available to remove any items loaded on to the target system by the application.
From the ‘Processing’ area in the ‘Execution’ tab, click the ‘Reset’ button. This will pop up a “Configure Processing parameters” screen where user can select the number of items to reset and the number of threads to execute this action. Click the “Ok” button to initiate the Reset action.
On completion of this process all relevant items will be deleted from the target system
Reset Items – Progress dialog
Clicking on the “Erase” button deletes all of the discovered items related to the selected Migration Task from the database. Any data loaded to the target will remain as is however the application will no-longer know whether it had loaded them. It's advisable to perform a “Reset” to rollback the loaded items from the target before clicking on the “Erase” button, alternatively if an “Erase” operation has already been done the has already been done the items can be manually deleted from the target.
Start erase of selected task
A ‘History’ button is available on each area for Discovery and Processing. Clicking on this button brings up a screen that list all of the actions that were performed on that migration task along with date the action was performed and the outcome of that particular action.
