Cannot upgrade Exchange organization from Exchange 2010 to Exchange 2013. While clicking the button Upgrade to Newer Exchange Version under Services > E-Mail > Exchange > Organizations the following error is displayed:

Could not find a 'Exchange2013Mailstore' server with enough capacity to add the additional services. Please contact your vendor to resolve this issue.


In order to perform an organization upgrade the hosts with Exchange 2010 and Exchange 2013 should have similar provisioning attributes.

On attempt of upgrade OA is trying to find suitable hosts using provisioning attributes specified in the service template used for subscription. In case if provisioning attributes are not the same for Exchange 2010 and Exchange 2013 hosts with Exchange 2013 are excluded, therefore required services for Exchange 2013 will not be found and the error above will be thrown.


Ensure that provisioning attributes are the same for Exchange 2010 and Exchange 2013 hosts and repeat the upgrade procedure.
