Archive Shuttle 11.4 - Planning Guide

Planning for migrations to Azure Blob

If you plan to migrate data to Azure Blob, install the Storage Import Module before beginning.

You’ll use the Storage Import and Storage Provider target when configuring the workflow policy, mapping wizard, etc.

While setting up the migration, use the Storage Import Module tab of the System Configuration page to, for example, set item/archive parallelism, set up conversion of MSG to EML, fail items permanently on specified errors, etc.

Planning for migrations to Enterprise Vault

When migrating data to an Enterprise Vault environment, it is essential that the option in the provisioning group to “Automatically enable mailboxes” is turned off. If it is not turned off, there is the possibility that duplicate archives may be created in the target.

Planning for migrations to Exchange

As with the ingestion in to Office 365, ingestion in to Exchange may be subject to throttling limits within Microsoft Exchange. A knowledge base article has been created which can help raise these limits.

By default the Exchange Import Module will attempt to ingest items into the chosen target mailbox or personal archive three times using AIP and then will fall back to trying Exchange Web Services (EWS). If they all fail, then the ItemRoutingErrorCount will be incremented, and the item will be counted as failed (and it will be visible on the Failed Items screen, and retried from time to time).

Planning for Office 365 migrations

Microsoft throttles connections and bandwidth usage to their cloud service – Office 365.

There are some steps that can be taken to improve the throughput and performance when migrating to Office 365. These are described in this section. In addition it is recommended that Microsoft be contacted and a request made to increase the throttling limits whilst the data migration is being undertaken.

Mailbox or Personal Archive

When planning your Office 365 migration, it’s important to discuss if you are migrating to either a mailbox or a personal archive. If you’re migrating to a personal archive, this must be enabled previously to your migration.

Remember that there might be different size and item limits on either choice.

Item size limits

There may be size limits set by Microsoft on your mailboxes when being ingested into Office 365. For more information on this, including how to increase mailbox size limits, see Size Limits When Ingesting into Office 365.

Authorization

You must use OAuth to authenticate when using Archive Shuttle. For more on OAuth, click here.

Throttling

You may need to lift throttling restrictions for your project. Restrictions are set by Microsoft, but lifting them for a set period of time (30, 60 or 90 days) is a straight forward process. Check out more on this here.

Mailbox or Personal Archive

Remember that there might be different size and item limits on either choice.

Item size limits

There may be size limits set by Microsoft on your mailboxes when being ingested into Office 365. You can, however, increase the size of the mailbox.

Journal Transformation/Journal Splitting

Migrating journals requires thought on whether you would like to process them as Journal Transformation, or journal splitting. For more on this, click here.

Migrating leavers

Migrating leavers to Office 365 takes further consideration. For more on this, click here.
