Councils about 7.5.4 -> 8.6 Migration

[redprive]

Hi,

I have a dedicated server with Plesk 7.5.4 and I'm going to buy a new server where I will install Plesk 8.6.

I have read this forum and I see that I can have problems with migration utility and I want to be very sure in all steps migration process .

Can you give me all councils to do it with security?

Thank you very much
