I like that this tool is very fast when migrating my DBs from one server or hosting provider environment into another so we do not have downtime during our migrations process which helps with business continuity as well! Also there are multiple vendors supported but some products seem geared more towards larger companies while others cater mainly for smaller businesses (in terms of number users).
This could potentially cause issues depending upon how large/small they want their user base at any given time - however having several options allows us flexibility without being limited by size constraints due to cost reasons etc..
