[ZendTo] [Data migration from old installation]

[Jules]

Peter,

Basically what Stéphane said, but with some important additions:

1. Comment out the cron jobs in /etc/cron.d/zendto and then restart 
crond on both your old and new servers before you give them both access 
to the database.
Failure to do this will result in the overnight cleanup job *wiping all 
your drop-offs and/or database records* of them.

2. After you've copied all the /var/zendto stuff over to your new 
server, then assuming your new server is using SELinux (which it will be 
by default), you need to reset the SELinux attributes on everything 
under /var/zendto.
Fortunately this is very easy. On the new server, as root do
     restorecon -FivR /var/zendto
Obviously you'll need to make sure the basic owner, group and 
permissions are correct after your rsync (or however you're getting them 
there), but things won't work unless you do the restorecon above as 
well. "ls -Z" shows you the SELinux attributes. The "-FivR" options make 
it recurse and show you any files it changes the attributes of.

Cheers,
Jules.
