Overall Review –
Binary Tree –
Cross forest Exchange to Exchange migrations happens with Ease .
OST Preservation is Unique.
It can provide rich Co-existence. (Note: This review covers only E2E (Exchange to Exchange Migration product from binary tree)
It can does the job perfectly for Exchange to Exchange migrations.
Lacks in user friendly interface but fits within the criteria for migration.
Can be used only for data migration.
Pre and Post migration activities needs to be taken care manually.
Best Suitable solution for Service Providers and Small/medium businesses who can do a Cutover Migration
(Same tool can be used for many platforms)
