This blog focuses:
-
Security migrate mailboxes;
- After migration safely uninstall exchange 2010;
How about this case all the tools coexistence environment to build and can be used to access the needs of a blog: Based on exchange 2010 migrate exchange 2016 to build a coexistence environment
First, case studies
1, case Overview
In this case the network uses Windows Active Directory to manage network resources, all versions of Windows servers are Windows server 2008 R2, one of the servers running exchange server 2010 mail system, responsible for enterprise e-mail communications. With the continuous development of business, the increasing scale of business, the diversity of user requirements leads to the function and performance of existing mail systems have become increasingly stretched. After comprehensive consideration, the enterprise decided to purchase a new server, the mail system upgrade. For this reason, research upgrade program are as follows:
1）新服务器的操作系统选用Windows server 2016，邮件系统选用exchange server 2016。
2）对exchange 2010服务器进行整体备份。
3）因为不能从exchange 2010本地升级，所以先实现两个版本共存。
4）共存环境下，迁移用户邮箱与相关功能至exchange 2016，并保持一段时期的稳定。
5）稳定期过后，卸载exchange 2010服务器。2, case pre-knowledge
1) coexistence environment
Since 2010 exchange 2016 and exchange of different architectures, so I do not support upgrading from the 2010 local exchange, which means you must deploy a coexistence environment. The purpose of the deployment is coexistence environment you want to migrate exchange 2010 mailboxes and other functions related to the exchange 2016. Before deploying coexistence environment, make sure that the forest functional level is at least Windows server 2008, exchange 2010 SP3 installation of at least UR11 patches.
2) to migrate mailboxes
Coexistence environment, the two mail servers have their own mailbox database, we need to exchange 2010 mailbox database mailbox migration to exchange 2016 mailbox database in. And after the migration is complete, the operation management of all mailboxes, mailbox data exchange should be in 2016 were, to be stable over time, the database will be deleted exchange mailbox 2010.
3) uninstall exchange 2010
In addition to the mailbox database, exchange 2010 also provides users with other services, can not be directly unloaded, or the whole mail system will be abnormal. So, before you uninstall exchange 2010, related services should be deleted. For example, an address list of services provided to clients by IIS virtual directory, OWA, auto-discovery, as well as offline address book and so on. These service when properly deployed coexistence environment, exchange 2016 have been able to provide normal.
Second, the implementation of case
1, the deployment of a coexistence environment
1) Active Directory Requirements
Ensure that the DC / DNS to work properly, the forest functional level to at least Windows server 2008, this case raised to Windows server 2008 R2. Specifically, how to build a coexistence environment may need to refer to the reference Bowen based on exchange 2010 migrate exchange 2016 to build a coexistence environment .
2) Confirm exchange 2010 to work
-
Install exchange 2010 SP3, create a test mailbox and send and receive test messages to ensure normal.
- To exchange 2010 SP3 overall backup server. Operation little.
2, began to migrate exchange 2010 to exchange 2016
Exchange 2010 coexistence within the test network environment 
Tom bob receive e-mail reply to 
test exchange 2010 extranet environment coexist 
Marry receive messages and reply to bob 
test exchange 2016 extranet environment coexist 
Marry receive and reply to e-mail a tom, a coexistence environment no problem, the next began to migrate 
to migrate an offline address book 
migration to accept the connector 
migrate send connector, remove DC2 server, add the DC01 can 
configure the DNS server queries 
migrate virtual directory 
migration is complete, click the Close button 
to migrate user mailboxes 
choose to migrate users 
to create a migration name 
remain By default, the new can 
wait for synchronization to complete 
the migration is complete 
send a test message, whether the normal mail migration is complete 
uninstall exchange 2010 mailbox database 
to delete the mailbox database directory 
Removing IIS virtual directory 
When removal is complete 
uninstall exchange 2010 
uninstall is complete, shut down the computer exits benet.com domain to 
domain controller DC2 removed 
modify internal and external DNS 
to modify the public network DNS 
Add host 
New alias 
new MX record 
configuration is completed clear the DNS cache restart the 
OWA logon test sending mail outside the network and received normally 
modify client login
Whether the client inside and outside the network normal communication test
So far migrate exchange 2010 to exchange 2016 migration have all been completed, and can receive and send mail.
