Run Database Integrity Check or Skip during Upgrade?
I'm planning on upgrading our Zimbra 4.5.8 FOSS installation to 5.0.1 during this coming weekend. We have what I consider a pretty large mail store (~135 GB). As far as I know we have no major issues with our current installation. Based on what I've read in these forums I'm expecting a rather lengthy upgrade process (several hours). So, my question is when the "database integrity" prompt comes up during the upgrade process should I answer "Y" or "N"? I'm assuming that based on my mail store size the check could add significant time to the upgrade process. What is the risk in skipping the check? If there are existing problems with my database they are not presenting themselves in any noticeable ways now. Does skipping the check just mean that any problems would continue to exist, or does it increase the chances of the entire upgrade process failing, or is the database going to be "fixed" anyway due to the version change?
Think twice before going to ZCS 5.0.1
In hindsite I would sit tight for one or two more interations of 5 before I moved off of 4.5x.. unless there is a strong compelling reason. There are some real deal breaking user facing bugs in 5.0.1 some over a month old that really annoy many of our users. Look over the bug list for 5.0.1 and make sure none of these are deal breakers for you.... then read over the bug list again just to make sure. I went from 4.5.9 to 5.0.1 rather smoothly with a database integrity check no problem doing it just to make sure.
No disrespect - Just a couple of pennies
I don't want to hijack this thread with my top 10 bugs. Let's just say when you walk on the edge sometimes you bleed a little. ;)
I only have a 8G mail spool and the integrity check was fairly quick and painless.
