[horde] Two installations of horde consolidated in one

[Paul Ronald]

Hello,

i have two independence installations of Horde for two Organizations. Now
the two Organizations (A and B) are merging and i need to integrate the
users of OrganizationA into the installation of OrganizationB. Both
installations has "Horde Groupware Webmail Edition 1.2.XX"

There is any procedure to migrate calendars, notes, etc for this scenery?.

Thank you.
Paul.
