Upgrading from ZCO 6.0.4 to 6.0.6

[mm2]

Is it legal and fully supported by Zimbra to upgrade from ZCO 6.0.4 to 6.0.6
without upgrading the ZCS server. We use the ZCS server 6.0.4 Network Edition.

Best regards.

As for legality, I doubt anyone will cart you off to jail if you use ZCO 6.0.6 with ZCS 6.0.4. Technically, we don't really support newer ZCOs with older servers. In this case, it would probably work OK, but it really isn't fully supported. But in cases like this, I'll bet people do it all the time. It's obviously more of an issue if you used a 6 based ZCO with a 5 based server. Also, there were some new features put in around 5.0.7 that precluded use with older servers back then, but again, in this case, it would probably work fine.

We use ZCO 6.0.5797.4 and we are currently victim of the bugs 43432 and 43433 as other people have reported for example on this post:

Sync error: MailServiceException$NoSuchItemException: no such message

Therefore, we need to upgrade our ZCO to solve this problem.

that the patch 6.0.5817.4. is available on the support portal.
Unfortunately, this patch no longer seems to be there! I do not find it in the
"Zimbra Utility and Beta Downloads" section.

Can you tell me if this patch is still available somewhere and if not what I can do to solve this problem since upgrading to ZCO 6.0.6 is not officially supported by Zimbra ?

Older versions of the Connector aren't usually kept on the support portal. I'd suggest you download the current Connector and try that on a test account to see if you have any problems.
