[horde] Migrating user data from an old horde instance to a new installation

[Christian Schoepplein]

Hello,

I have a damn old horde installation which has to be migrated to a 
current setup.

Old installation:

  * Gollem: H3 (1.0.2)
  * Horde: 3.1.4
  * Imp: H3 (4.1.4)
  * Ingo: H3 (1.1.3)
  * Kronolith: H3 (2.1.4)
  * Turba: H3 (2.1.5)

New setup:

  * Horde: 5.2.13
  * Content: 2.0.5
  * Gollem: H5 (3.0.10)
  * Imp: H5 (6.2.17)
  * Ingo: H5 (3.2.13)
  * Kronolith: H5 (4.2.19)
  * Nag: H5 (4.2.13)
  * Timeobjects: 2.1.3
  * Turba: H5 (4.2.18)

Migrating and adapting the config from the old to the new system causes 
me no trouble, but I am not able to migrate all the userspecific data 
stored in the mysql db backend.

for that reason I see two possebilities now:

1. Try again to migrate the database from the old horde setup to the new 
   installation. Because I have no idea what went wrong during the 
   first try, it is very likely that I will run into the same issues 
   again :-(.
2. Start the new installation with an empty database which will be OK, 
   if I at least can migrate the addressbook entries from the old to 
   the new installation. What steps are necessary to do this? Would it 
   also be possible to export the adressbook entries into e.g. vCards, 
   csv files or whatever and import them into the new system via a 
   script or so?

Any help or hints how to migrate the adresses would be great!

Thanks and have a nice weekend,

  Christian
