<html>Dear Wolfgang,<br /><br />Firstly thanks for your answer, secondly I have one more doubt, during this time where the new Mupdate Master is receiving mailboxes information from backend servers, is necessary stopping comunications between frontend servers and mupdate master or none action is necessary besides that one you've mentioned before?<br />We're concerned if frontend servers will connect to Mupdate Master and receive from it an information which there's no mailboxes anymore until the backend push entirely mailboxes information and this situation to cause any trouble.<br /><br />One more time, thanks<br /><br />Cheers!<br /><br />--<br /><br /><font size="3"><b>Miguel Moreira</b></font><br /><font size="3">DTE/SRE/GRE - Gerência de Redes<br />+55(31)3339-1401<br />PRODEMGE - Companhia de Tecnologia da Informação do Estado de Minas Gerais</font><br /><br /><br /><font size="2">Aviso: Esta mensagem é destinada exclusivamente para a(s) pessoa(s) a quem é dirigida, podendo conter informação sigilosa e legalmente protegida.

Shouldn't take that long since we did it with 130k<br />on 8 backends in under 20 minutes (or even shorter).<br /><br />Greetings, Wolfgang<br />--<br />Wolfgang Breyha <wbreyha@gmx.net> | https://www.blafasel.at/<br />Vienna University Computer Center | Austria<br />----<br />Cyrus Home Page: http://www.cyrusimap.org/<br />List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/<br />To Unsubscribe:<br />https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus</blockquote></html>
