Dear's,
I need your suggestions and best practice to move frm EV 9.0.3 to EV 10.0.3
Our existing environement hasEV 9.0.3 on windows 2008 SP2 and Exchange 2007 with around 3000 mailboxs archived , we are planning to move to exchange 2013 and EV 10.0.3 along with new SQL server on completely new hardware.As EV 9.0.3 does not support Exchange 2013 so need your suggestions.
I am planning as below:
1. Install new EV 10.0.3 along with Exchange 2013
2. Disbale all 3000 users in EV 9.0.3
3. Move all 3000 users mailboxes to exchange 2013
4. Enable archiving for users in new EV 10.0.3
5. Use move archive option to move 3000 users old archive from EV 9.0.3 to EV 10.0.3
My worry is , once I disable the users in EV 9.0.3 and enable them in EV 10.0.3 then will they able to acess the old archive from EV 9.0.3 without any issue as I would be requiring large amount of time to move 3000 users archive to EV 10.0.3 maybe a month time.
