Affirmative.
Data portability is one of the great strengths of Zimbra.
Not only is it straight forward to migrate into Zimbra from other
mail servers, but also from Zimbra installation to Zimbra installation.
Because 01.com is not only an authorized Zimbra hosting provider, but
also an integrator authorized to sell Zimbra licenses for the same
price, with the same discounts as Zimbra itself, we can start your
company in the shared environment and move you to a dedicated server,
or to your own server at your office, or data center, when you're ready.
What's more, if you've been hosting with us at least 6 paid months,
the migration itself is free-of-charge, you just pay our standard rates
for installation, and any other services you may choose to use, such as
maintenance, and help desk support. When we migrate your services, you
can take all of your data with you, including any archives you may have
created using Zimbra's Archiving and Discovery.
