If you have customized role assignment policies in Live@edu Microsoft Exchange Online, you should document them prior to the upgrade, and then set them up again after the upgrade is complete.

• In Live@edu Exchange Online, there are two role assignment policies possible: RoleAssignmentPolicy-DefaultMailboxPlan and RoleAssignmentPolicy-GalDisabledMailboxPlan. Both policies can be customized.
• During the upgrade, the HiddenFromAddressListsEnabled setting will be automatically set as a flag on the individual mailbox of everyone who was assigned the RoleAssignmentPolicy-GalDisabledMailboxPlan policy in Live@edu, so these users will not show up in the global address list. However, no customized settings will be maintained.
• In Office 365 Exchange Online, you can create new role assignment polices and assign them to specific groups or mailboxes. It’s possible to have more categories of users. This is useful for creating settings for groups of users, such as students, faculty, and staff.    
• For more information, see Role Assignment Policies in Exchange Online.

Document role assignment policies settings prior to upgrade

• Using Exchange Control Panel
  1. To view the role assignment policy assigned to a specific user, go to Manage My Organization > Users & Groups > Mailboxes. Select a user, click Details, expand Mailbox Settings and document the role assignment policy listed for that user.
  2. To view the end user roles assigned to each role assignment policy, go to Manage My Organization > Roles & Auditing > User Roles. Double-click each role assignment policy, and document which end-user roles are enabled in that policy.

• Using Windows PowerShell in Exchange Online (in bulk)

1. Export a list of users and the role assignment policies assigned to them by running Get-Mailbox –ResultSize unlimited | select UserPrincipalName, RoleAssignmentPolicy | export-csv [path to file] .

Here's an example:

Get-Mailbox -ResultSize unlimited | select UserPrincipalName, RoleAssignmentPolicy | export-csv "C:\Desktop\EduMailboxPlans.csv"

2. Save a file containing the end user roles assigned to a role assignment policy by running Get-RoleAssignmentPolicy [policy name] | select -ExpandProperty AssignedRoles > [path to file]

Here are two examples:

Get-RoleAssignmentPolicy "RoleAssignmentPolicy-DefaultMailboxPlan" | select -ExpandProperty AssignedRoles > "C:\Desktop\RoleAssignmentPolicy-DefaultMailboxPlan.txt"

Get-RoleAssignmentPolicy "RoleAssignmentPolicy-GalDisabledMailboxPlan" | select -ExpandProperty AssignedRoles > "C:\Desktop\RoleAssignmentPolicy-GalDisabledMailboxPlan.txt"

Re-create role assignment policies after upgrade
