    Default Zimbra upgrade

    Hi,

    We are using ZCS 4.5.10 version on RHEL5 - 64 bit in production environment and one domain is working fine. SMTP relay has been configured on different server.

    First time i am going to work on zimbra. I found that we are using very old version and latest version is zcs 5.
    Can you please tell me what are the additional features it has than the old one ?

    I searched on net and found that to upgrade this version, I have to only select upgrade ..that's it and it will automatically upgrade .

    Is this that easy ? How much downtime it will required ? Is there any possibility to loose data, contacts ? what steps client need to do at there end after upgrade?

    Thanks,

    Kanchi

    First thing take a backup! In fact take a couple of backups The time to upgrade will very much be dependant on how many mailboxes you have and how much data. Is this a single or multi server install ? If multi then I would recommend upgrading to 4.5.11 first and then too 5.0.11. If single, then you can just run the install script for 5.0.11 and all should be good. With respect to new features then there are lots

    Thanks for the reply.

    we have around 200 accounts. And as I have mentioned in production environemnt we have 2 servers where zimbra has been installed. One of it has been used for SMTP relay. so pls suggest.

    We have one test enviornment so I can test upgrade on that.

    And one more question. how many domain we can configure in zimbra ? as in near future we have to configure multiple domain in one server to support different client.

    Thanks

    I believe you shall need to upgrade to 4.5.11 first, and then upto 5.0.11. With respect to domains you can run thousands, but remember to check your system resources aswell.
