[zenoss-users] Planning a 32-bit to 64-bit migration

[James Roman]

We are planning on migrating from a 32-bit Zenoss 2.2.4 install to a 64-bit Zenoss 2.3.2 install (on a new server). I've read the upgrade instructions but do not see any special  instructions. My upgrade plan looks something like this. Record and document internal zenpack components, custom graphs, etc. Install new 64-bit Centos 5.2 server with 2.3.2 stack installer Backup existing 32-bit Zenoss 4.6 server using zenbackup Upgrade existing 32-bit Zenoss 4.6 server using el4 RPM and RPM upgrade process (including migrating database) Test 32-bit Zenoss 2.3.2 install Run zenbackup on 32-bit install and copy to 64-bit install run zenrestore on 64-bit instance There are some differences between the 32-bit net-snmp and rrdtool packages, which could be consequential when monitoring. The obvious difference is in size of integers that can be processed. This may be irrelevant if Zenoss itself does not handle/allow 64-bit numbers. Does anyone know if the are any special migration steps for the RRD files to make them capable of storing larger numbers? (export the data inside the RRD files to an xml file, create 64-bit rrd file, import historical data, etc)? Are there any additional steps that one might need to take to migrate from 32 to 64 bit installs. -- James D. Roman Sr. Network Administrator Science Systems and Application, Inc.
