6.5.6 upgrade to 7.5 latest MP

Hello and Good day fellow Netbackup users,

Can someone please confirm if this is supported

Currently running in PROD

Windows 2003 SP 32 bit Server OS with Netbackup 6.5.6

Would like to go to 7.5 and or 7.5 latest MP on this server?

Is this setup supported for this upgrade to 7.5 Latest MP or do we have to go to 7.0 first then upgrade to 7.5?

Thank you

Stef
