Let's say we have three domains: domaina.com, domainb.com and domainc.com. They have no trust between them.
Initial situation
Domain A: Active Directory with 2008 R2 & Exchange 2013
Domain B: Active Directory with 2008 & Exchange 2007 SP2
Domain C: Active Directory with 2012 R2 and with Office365, OneDrive for Business & Sharepoint Online
Migration
They want to migrate together to one unique domain domaind.com: emails, accounts, Sharepoint, OD4B.
Questions
- Is it possible to migrate an existing Sharepoint Online to a new one into a new Office 365 ?
- About OD4B ?
- I've found cloudmigrator365 for O365-O365 migration, but it is really expensive. Is there any other solution ?
- Is it possible to migrate the different Active Directories into the same domain ? I mean, instead of having domaina.domaind.com and domainb.domaind.com, we should simply have domaind.com.
Thanks in advance for the help you will provide.
