The ease of use with the customer service team at iVentures was amazing! They were extremely helpful every step along our journey to migrate from LotusNotes 8 & 9 to 10+.
We also liked that we could choose whether or not to upgrade the data as well after migrating. This allowed us some flexibility when deciding how much storage space would be needed once migrated - which turned out great considering this information isn't readily available until you're very close-to completion! It's worth noting here too if it helps any others reading about moving their mail systems away from lotusnotes they can set up rules/quotas within notes itself using filters (like keywords) so there are no longer "black lists" required by other products like outlook etc., just keep those same filter words used previously (ie.: keyword). Easy transition process between versions; easy transfer across email domains without losing messages / folders during move.
