I just sent a mail to all mailboxes , so lmtp delivery will do a Index 
Reconstructing will be much heavier , I think.

Is there a way I can do a Index-upgrade only ?

Also I have a few more servers to upgrade .. but if this is going to 
take so long , upgrade may not be possible. Only if I could upgrade the 
Index before really upgrading cyrus then this would work
