Exchange2007 Upgrade to Exchange2013 (8)-Migration considerations

First, pre-preparation

1. Considering the large amount of data during the post-mailbox migration process, the new Exchange 2013 server is equipped with large bandwidth to ensure smooth data migration.

2. To ensure that the deployment fails, you can roll back the old Exchange 2007 system to the correct state, and make a full backup of each Exchange 2007 server.

3.

Ii. Deployment Coexistence Considerations

1, after the deployment completed Exchange2013 server, it is recommended to create a new Exchange 2013 Administrator account, the account will be in the domain admins,enterprise Admins,schema admin,exchange Organization administrators,organization Management. Or only under the next two user groups. This account is used to log in to the EAC in exchange 2013 to manage the new server and to use the original Exchange 2007 administrator to manage Exchange 2007 servers, which can be deleted after the full migration is complete.

2, switch the Exchange 2007 inside and outside the network URL, set the DNS host name and so on during the off-hours, and many people cooperate to do, to ensure the minimum downtime of the Exchange server.

Third, mailbox migration considerations

1, migration can be divided into batches of migration, such as by the department or by the first letter, such as the wrong order.

2, in order to ensure the speed of the migration process, it is recommended to use the "XXX document 7-Change Concurrency" method to change the number of concurrent.

You can also simply open a few more EMS and execute the migration command in each EMS.

3, all the relocation work in the group after work, to reduce the impact on users

4, hr all mailboxes within this OU are migrated to the Exchange2013 13maildb01 database, and you can enter the following commands in EMS:

C:\windows\system32>get-mailbox-organizationalunit ' HR '-resultsize Unlimited | New-moverequest–targetdatabase ' 13maildb01 '-baditemlimit 50

650) this.width=650; "title=" clip_image002 "style=" border-top:0px;border-right:0px;background-image:none; border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;padding-right:0px, "border=" 0 "alt=" clip_ image002 "src=" http://s3.51cto.com/wyfs02/M00/83/8F/wKioL1d2BpKi6z35AACNHlME714069.jpg "height=" 214 "/>

This command uses PowerShell redirection to query mailboxes within the OU for HR, and then migrate them to Exchange2013 one after the other.
