Zenoss Stack 3.2.1 -> 4.2

Does anyone have a guide or steps to upgrade zenoss-stack 3.2.1 to 4.2?

 

After reading the latest docs it seems the instructions are for the 3.2.1 rpm version of zenoss - but not so much the stack.

    As stack installers are no longer being built, I'd recommend approaching this as a two-step process -- first, migrate to a 3.2.1-based installation using RPMs. Then upgrade the RPM installation to 4.x.

    I too have the same issue.  Running  Zenoss 3.2.1 on OpenSuSE 12.1 with Stack installer.  Want to upgrade to 4.2.

    Like Shannon, I am running ZenOSS 3.2.1 on a stack installer system (Ubuntu) and would like a migration path to 4.2 - will that be available?  We currently have 300+ switches that have been modelled for over 3 years and I would hate to have to re-do all that work and lose all the historical data.

    The basic process for upgrading from a stack installer is a two-step process, and we will be providing more detail on this on the wiki (wiki.zenoss.org) soon. But this will give you a basic overview of the process. First, you will need to migrate to 3.2.1 64-bit RPMs running on RHEL/CentOS 5. So here are the steps:

     

    1. On your existing install (stack installer) of 3.2.1, use zenbackup.

    2. Set up a new install of RHEL5/CentOS 5 3.2.1 64-bit using our standard RPMs, on a new system.

    3. Use zenrestore on the new system. If your stack installer was 32-bit, you will also need to convert your RRD data over to 64-bit (extra step, more info to come on the wiki on how to do this.)

    4. Verify your new zenoss 3.2.1 64-bit RPM install is now running fine.

    5. Follow instructions in our Core 4 Installation Guide to upgrade 3.2.1 RHEL/CentOS 5 64-bit to 4.2.0 (Core 4.)

    6. Verify proper operation.

    7. Now you can decommission your stack installer 3.2.1 Zenoss.

     

    (Now, optionally, you can zenbackup/zenrestore to jump to RHEL6/CentOS6.)

     

    This will be easier to do if you have access to virtual machines.

    We've try to migrate from CentOS 5 / Zenoss v3.2.1/64bit  to CentOS 6 / Zenoss v4.2 64bit using zenbackup/zenrestore commands but new database is empty and there is no devices. Can you please post detail instructions for this step because in Core 4 Instalation Giude there is no detailed instructions.

    Hello,

     

    I have try follow your website but seem getting a lot of error after restarting Zenoss.. it looks like the Zenrestore command did restore all previous configuration too?

     

    Do you have any notes how you modify the configuration file after done?

     

    Regards,

    Kelvin Lo
