Attention Session en Anglais, animée par Scott Schnoll, Senior Content Developer à Microsoft Corp. Cette session vous expliquera comment architecturer une migration vers Exchange 2013 depuis d'ancienne versions d'Exchange avec comme speaker Scott Schnoll, Gourou Exchange en provenance directe de Redmond. La coexistence de serveurs de versions différentes sera aussi abordée.

  • Enable Outlook Anywhere on all legacy CAS to allow 2013 CAS to discover and proxy through rpcproxy.dllEnsure IIS Authentication Methods on legacy CAS have NTLM enabledMake sure external hostname matches for legacy CAS and 2013 CAS
  • Make sure to point out 2007 EAS users are proxied 2013 CAS  2013 mailbox  2007 CAS  2007 mailbox
  • Batching capabilities is now extended to Exchange On Prem (just like we have had in O365 for some time).Allows for retry semantics and ability to batch users for moves to Exchange 2013.Workload Manager will throttle moves to maintain a positive end user experience. This can reduce the rate of user mailbox moves.
  • Now let us look at the steps for migrating public folders from 2007 or 2010 to 2013. This is an overview and we have interactive session where we can go into details on a specific step.Up here you have the 2007 and 2010 PF deployment which we will migrate to a 2013 PF deployment.1. PreparationThe first step of preparation is about ensuring that the existing Exchange environments is prepared to handle the migration. The coexistence updates are needed on all 2007 and 2010 servers across the organization. All users who require PF access should first be moved to 2013 servers.2. AnalyzeNext you should analyze the existing public folder deployment. Like the structure, item counts in public folders, permissions. We recommend taking a snapshot of this information so you can validate it later when the data is moved to 2013. A mapping then needs to be created where public folders are mapped to their host mailboxes. Things to consider when assigning public folders to mailboxes are existing size, room for future growth, proximity to clients. At release we will have some scripts which will help you create the mapping.3. Create PF mailboxesOnce the mapping is done, the PF mailboxes need to be created on the 2013 servers. In order to distinguish between mailboxes being created pre and post migration, they need to be stamped with a HoldForMigration attribute.4. Start the migrationNow we are ready to begin the migration. This is done by creating a migration request. The input to the migration request is the mapping which we created in step 2. This begins a data copy from the public folder databases to the mailboxes. It happens in the backgound and clients will still continue to access the existing PF deployment. Once the copy is complete the migration request gets into an AutoSuspended state where it will remain till the administrator takes the next step which is to finalize the migration request.5. FinalizationNow the finalization step will need to be planned over a downtime. First a quick update to the snapshot which we took in step 2 is recommended. Then the finalization will happen in two steps. First the administrator will set a flag locking the source public folders. This will trigger a logoff of all user clients. Following that the administrator needs to wait for replication to complete. Then the second step would be to initiate a finalization of the migration request. This will do a final sync to make the 2013 data current and complete the switch over of clients to 2013.6. ValidateThe last step is q validation to make sure all data has been migrated. The snapshot data from the earlier steps can be used to validate this.-----------------------------------For QA and more detailafter migration is possible, but performing this step could lead to a loss of public folder data since any changes to public folders after the Exchange 2013 Preview migration was finalized will not be reflected in the Exchange 2010 public folders. In addition, as part of the rollback, we recommend that you remove any Exchange 2013 Preview public folders that were created as part of the migration process.For the migration of a geo-distributed hierarchy, how can I ensure that the public folders are created in the location nearest to the target users?As part of the migration process, a CSV file is generated (using the publicfoldertomailboxmapgenerator.ps1 script) which contains the folder to mailbox mapping for the new hierarchy. You can then use this CSV to create public folder mailboxes in the appropriate geographic location and modify the CSV file to have the required folders in the appropriate mailbox so they are near the target users.Draft PF FAQ, document any additional questions that are not on this list for Andreahttp://technet.microsoft.com/en-us/library/jj552408(v=exchg.150) SP3 is required to migrate from 2010 and coexistence RU is required to migrate from E12. It contains code in store which triggers during migration to kick off clients and keep them out till the migration is complete. It also has code to send clients to Exchange 2013 after migration is complete. It also has code to allow transport to understand Exchange 2013 PFs when delivering mail to mail enabled PFs in Exchange 2013.

  • Tool available to analyze existing Public Folder hierarchy to determine how many Exchange 2013 Public Folder mailboxes are recommended Users continue to access existing Public Folder deployment while data is copied Data migration happens in the background There will be a short downtime while the migration is finalized Once migration completes, everyone switches at the same time Can switch back, but any post migration Public Folder changes are lost

  • Manage Exchange 2013 mailboxes Manage Exchange 2013 certificates Manage Exchange 2013 servers Manage some Exchange 2007/2010 server attributes View and update Exchange 2010/2007 mailboxes and properties (with a few limitations)
  • This is due to more accurate space usage calculation of items within the database compared to previous versions Expectation is 30% increase in quota hit, but will vary based on the content types May want to increase the quotas of any user using 75% or more of their quota prior to moving their mailbox to Exchange 2013 The database size on disk does NOT increase
