migrating zarafa to a new kopano server

[AnotherAndy]

Hi Simon,
did you check this here out? This is a very good manual.
https://documentation.kopano.io/kopano_migration_manual/zcp_migration.html
What exactly is your problem with migrating the users?
My biggest problem while migrating was to move the users from the old to the new LDAP Server. You can find it here:
https://forum.kopano.io/topic/442/ldap-migration-zarafa-kopano-not-working/7
-> check out my latest post :)
Good luck
best regards
Andreas

Dear Andreas ,

Thanks a lot for the quick reply
I will check it out and let you know

Just for test I did create a new user using the kopano cli command and kopano configured to use db pluggin and I was succesfully able to login into webapp

since I have abt 200 email users on my old working zarafa server i need to login into webapp with the existing users

the first link I believe is migration of zarafa to kopano on the same server
but for me i want to move the users to the new server so my existing users can log into webapp and see their mail
aslo my old zarafa server was installed using yum and configured via yaffas zadmin web tool.

Hi Simon,

I used http://phpldapadmin.sourceforge.net/wiki/index.php/Main_Page to verify my users on the new system.
I’m no sure if the kopano CLI uses the openldap server to store the users.

I recommend to first transfer all users to the new openldap Server and verify if they all exist.
If yes you can continue with the “zarafa to kopano” skript.
https://documentation.kopano.io/kopano_migration_manual/zcp_migration.html
Poiint 4.3.1
If you have a working openldap on the new server you can continue with the migration.
best regards

Dear andreas,

Hello Simon.

I think you want to migrate Zarafa with LDAP User to Kopano with local DB User.
Is that correct?

If you have local DB User, there is no need for a LDAP Admin Tool, as you simply have no local LDAP Server.
The users are stored in the database.

So you have a new Kopano Server and imported the mysql database and copied the attachments.
You also have create a local user with kopano-cli Tool.

The easiest way to get your e-mail is to attach the old store with the new user.
Take a look at following commands:
List all orphaned mailboxes:
“kopano-cli --list-orphans”

Now hook the store with the new local user:
“kopano-cli --hook-store=<STORE-ID> -u <USER>”

You can now login with the user and should see all emails again.

How many users do you have on the old Zarafa Server?

Hope this helps.

Kind regards

Dear Basti,

Really appreciate your reply but so sorry for my delay as i was out of office
I have imported the mysql database in my new kopano server and also copied the attachments
the import onto the new kopano server has gone through without any error
i have copied the attachments too

but when i use the command i see no stores

[root@kopano ~]# kopano-cli --list-orphans
Stores without users:
Store guid Username Last login Store size Store type
----------------------------------------------------------------------------------------------------
Users without stores (0):
User Full Name Homeserver Store

[root@kopano ~]#

on my new kopano server i had just created 3 users for test before i did import my mysql databse into new kopano server and those are the users I see as below

---

Dear Basti,

I did the below
after I had imported the mysql database from my running zarafa server onto my new kopano server i could not see any users or orphned stores as per my above post

but after little homework i changed my server.cfg to tell kopano server to use the new database which was named as zarafa
i could even see all my uses when i used to list them in mysql
but the kopano server refused to start showing the below message

As you see in log: To fix the excess rows, use kopano-dbadm k-1216.
You need to run:

kopano-dbadm k-1216

to fix this.

[sbdcunha]

Deat walter,

Thanks for you reply
just today morning i did run kopano-dbadm k-1216 and it took almost more than 2 hrs for the the task to be finished and now kopano-cli --list-orphans shows me the stores as shown below

[root@kopano ~]# kopano-cli --list-orphans | more

since the username field is blank i dont the which store belongs to which user so as to hook it
have about 400 users

appreciate your help and advice

thanks and regards

simon

[sebschremser]

Hello Simon.

Wow you have created 400 users on the command line?
That have must been a long work day.

First i would delete the 0MB stores with the following command:

for i in $(kopano-cli --list-orphans |grep "0.00 MB" | awk '{print $1}'); do kopano-cli --remove-store $i; done

After that i would hook the store to a dummy user, just to see which content is in the store.
When you know to which person the store belongs, you can hook it to the right user.

But thats a lot of work for 400 users.

Maybe the Kopano Staff knows a more appropriate and faster solution.

Kind regards
Basti

Hi @sbdcunha ,

just a thought from my side

@sbdcunha said in migrating zarafa to a new kopano server:

have about 400 users

would you be willing to get professional help? so someone who would properly migrate your ldap tree so you can just reuse your users and don’t need to rehook/recreate every user? such a person could then also help you with the rest of the migration and ensure proper performance on your new machine.

Some of the replies in this thread came Kopano partners who would probably help you out with your challenge. Or you could get in contact with our professional services directly (via our support).

[sbdcunha]

Dear Guys ,

appreciate your quick response .
dear basti i have not created the users but my old zarafa has about 400 users.
would also weigh the option to have to probably contact support for profesional services as mr felix says

thanks guys once again

regards

simon
