[SOLVED] Update from 8.0.0_GA to 8.7.x fails with LDAP errors

[Txalamar]

Hi,

after resolving some certificate errors with LDAP service I'm getting the following error during upgrade process:

Code: Select all

Sat Mar  4 13:28:35 2017 Starting ldap...
Sat Mar  4 13:28:35 2017 *** Running as zimbra user: /opt/zimbra/bin/ldap start
Failed to start slapd.  Attempting debug start to determine error.

Sat Mar  4 13:29:14 2017 failed with exit code: 256.
Sat Mar  4 13:30:51 2017 UPGRADE FAILED - exiting.

so I executed:

Code: Select all

/opt/zimbra/openldap-2.4.33.4z/sbin/slapindex -F /opt/zimbra/data/ldap/config entryDN

as stated in:
viewtopic.php?t=13551

After that I rerun the upgrade and I get:

Code: Select all

[] FATAL: failed to initialize LDAP client

Before this error I can find some others in the installation log file (both are attached, 1st and 2nd installation run):

Code: Select all

If I run a third time the update process it ends with no errors but there is obviously a problem because some services do not start, mainly mailboxd.

If someone can point me out to the root cause of that problem I would appreciate that a lot. I've been trying to perform this upgrade with no luck since time ago...

Thanks for your time!

Best, Pau.

Hi,

I got it. Just upgraded from 8.0.0 to 8.0.9, then to 8.5.1 and finally to 8.7.3.

No errors during the upgrade process and no errors starting services.

Looks fine!

Hi,
That's a good path for sure, from 8.0.0 sounds like a real big step, also we require at least 8.0.3 or above, as we made some changes in the ldap in that version, so jump to 8.0.9 and then from there to 8.5 or 8.6 and then 8.7 sounds great.

Best regards
