Mail upgrade by Policy via dialup

For our remote users, I’m going to send them Lotus Notes 7.0.2 installation CDs for them to upgrade their software. The users are assigned a desktop policy to upgrade their mail template. After the software upgrade, when the users connect via dialup, at what point will the mail file changes be replicated? Is it during the first replication? Or, does the authentication during the first replication trigger the mail template upgrade and then the changes are available to be replicated during the next dialup connection?

Thanks
