Migrate log database partitions from Web Security 7.1 to 7.8.4

Hi,

I’m half way through migrating from Web Security 7.1 to Web Security 7.8.4

So far I have built a new Windows 2008 R2 server and successfully installed Web Security 7.8.4

Policies have been successfully exported from Web Security 7.1 and imported into Web Security 7.8.4

Does anyone know whether it’s possible to migrate log database partitions from v7.1 to v7.8.4?

Thanks,

TPO
