    Default Moving from FOSS to NE server - mysql problem

    hi all

    we are trying to move from a Zimbra 4.5.11 FOSS server to
    a Zimbra 4.5.11 Network Edition server.

    We followed the steps in this link:

    Network Edition Moving from Open Source to Network Edition ZCS - Zimbra :: Wiki

    In step 4 of Preparing the Network Edition Server, after we ran the mysql -f zimbra < /backup/mysql.sql , we got these errors

    ERROR 1044 (42000) at line 20: Access denied for user 'zimbra'@'localhost' to database 'information_schema'
    ERROR 1044 (42000) at line 28: Access denied for user 'zimbra'@'localhost' to database 'information_schema'
    ERROR 1044 (42000) at line 29: Access denied for user 'zimbra'@'localhost' to database 'information_schema'
    ERROR 1044 (42000) at line 41: Access denied for user 'zimbra'@'localhost' to database 'information_schema'
    ERROR 1044 (42000) at line 42: Access denied for user 'zimbra'@'localhost' to database 'information_schema'
    .....
    .....
    .....
    ERROR 1044 (42000) at line 514: Access denied for user 'zimbra'@'localhost' to database 'information_schema'
    ERROR 1044 (42000) at line 516: Access denied for user 'zimbra'@'localhost' to database 'information_schema'


    --------------


    Any advice?

    We are thinking of installing 4.5.11 FOSS on the new server and then copying the contents in /opt/zimbra/db from the old server to the new server, instead of doing mysqldump and then importing it.
    Will this work?

    Thank you very much in anticipation.

    okay

    this is what i did -- seems to work

    mysql -u root -p [PASSWORD REMOVED] -v zimbra < /backup/mysql.sql

    for other peoples reference to get the mysql password you can run :-

    Code:
    su - zimbra
    zmlocalconfig -s | grep mysql_root_password

    No, not okay.

    got this 'error' message when doing as root. not sure if this is normal or not?
    usually this kind of output happens when the command parameters are incorrect.

    okay actually mysql -f zimbra < /backup/mysql.sql seems to work -- even with all the error messages


    but mysql -u root -p [PASSWORD REMOVED] -f zimbra < /backup/mysql.sql does not.


    but i do not know what is in the mysql database, and i don't know if the migration is successful -- because i used test servers and there aren't much data on them. what does the mysql database store? if it is just standard items, and i had used defaults, then perhaps the zimbra server will start okay when the mysql import is okay or not?


    Also when i did the slapadd, i got this warning message


    [zimbra@mail ~]$ /opt/zimbra/openldap/sbin/slapadd \
    > -f /opt/zimbra/conf/slapd.conf -cv \
    > < /backup/ldap.bak
    The first database does not allow slapadd; using the first available one (2)

    Holy Security, Batman! I've removed your mysql root passwords. Be careful what you post. We wouldn't want you to get hacked.

    the passwords are not the real ones. changed some of the characters.
    in any case, we were only using test servers.

    we wanted to upgrade to Network Edition but still could not figure an efficient way to do this.

    We have a Zimbra 4.5.11 FOSS running on Fedora 4 32-bit,
    and we want to migrate to another machine with Zimbra 5.0.2 NE on RHEL 5 64-bit.

    A Zimbra reseller suggested this:
    1) install 4.5.11 on the existing machine (4.5.5 FOSS on Fedora4).
    2) install RHEL 32-bit on an 'intermediary' machine and install 4.5.11 on it.
    3) Follow instructions to move from FOSS from existing machine to NE to 'intermediary' machine
    Network Edition Moving from Open Source to Network Edition ZCS - Zimbra :: Wiki
    4) Install RHEL 64-bit with 4.5.11 on new machine.
    5) Follow instructions to move from 32-bit to 64-bit
    Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki
    6) Upgrade to 5.0.3

    But this is not acceptable as we will need to have a 3rd machine.

    So we tested moving directly from 4.5.11 FOSS (on 32-bit Fedora) to 4.5.11 NE (on 64-bit RHEL). It seemed to work -- but there were the error messages as per the above messages.

    This is what we tested (on test machines with little test mail data and few users).

    1) Install 4.5.11 FOSS on Fedora 4 32-bit (to simulate our existing server -- old server).
    2) Install 4.5.11 NE on RHEL 5 64-bit on new server
    3) Follow instructions to move from FOSS on old server to NE on new server.
    Network Edition Moving from Open Source to Network Edition ZCS - Zimbra :: Wiki


    Any advice? Are the error messages important?
    Can we move directly from FOSS on 32-bit Fedora to NE on 64-bit RHEL?

    Thank you.
