I just attempted to upgrade our WCS software from 126.96.36.199 to 188.8.131.52. During the upgrade it kindly informed me that 184.108.40.206 is not supported on Red Hat 4. Therefore it would seem that I need to upgrade to 5.
But which task should i compelte first?
The linux upgrade or WCS?
The error mentions that 5.2 is not officially supported on linux 4. So does that mean I should do the upgrade to WCS and then upgrade Linux?
Just thought I'd post back what we did in the end.
1) Backed up DB and Licenses files
2) Set up new VM Instance running Red Hat 5.3
3) Shutdown old physical server (as the license is tied to the hostname we couldn't have both servers running at the same timeâ¦ I think this is something to do with Linux.. )
4) Change the name on the new server. Disable the redhat firewall.
5) Run the install script
6) Restore the DB (just remember to use binary FTP and not ascii when transferring the backup file. Ascii mode corrupts the tar file backup and you get an error during restore of âinvalid distance codeâ)
7) Restart services
The license files are included in the DB backup. If the you don not change the host name to match the original you will not be able to start the WCS services.
