That's perfectly normal, and I think it's even covered in the release notes... Nope, I'm wrong, the release notes mention the larger Memory footprint, due to more data and metadata being cached in memory. But the on-disk size increases, too, as there is more information being held in indexes, etc.
The same is true, again, when going from 2.5 to 3.X

Wolfgang,
If you don't mind, I'd like to know if when you upgraded backend servers from 2.4 version to 2.5 version you have an increase, in metadata size.Here we had 30% around of increase
Thanks one more time
Greetings

I recommend the follow steps:
*) check that your currently running setup has no conflicts in mailboxes.db
by running "ctl_mboxlist -mw". It is possible that you see output if
somebody changes his mailboxes while you run the command, but it should
not appear again if you run the command a second time. If everything is
fine...
*) shut down all running cyrus
frontends first, then backends and mupdate last
*) backup your mailboxes.db on mupdate server
*) replace/update mupdate and start it with empty/removed mailboxes.db.
*) backup your mailboxes.db on the backends
*) do the ctl_mboxlist -m by hand on the backends (only one at the same
time) you can check if everything went ok with "-mw" at any time
afterwards.
*) start cyrus on backends
In our setup the frontends have mupdate running as well. I can't currently
remember if this is mandatory. If this is true in your setup then:
*) remove or rename the mailboxes.db database on the frontends and start
them. They will fetch the database immediately from the mupdate server.
This is visible in syslog as well and takes about 30 seconds in our
setup (~250MB mailboxes.db).
otherwise
*) start the frontends
At this point everything should be up and running again.
Watching syslog output all the time usually helps.
IIRC we updated the mupdate server to 2.5 first. Then we had a mix of 2.4
and 2.5 backends for some time. The 2.5 backends had some capabilities
suppressed. Frontends had 2.4 until all backends had 2.5. Last but not
least we upgraded to 2.5 on the frontends.
If you need more info/details feel free to ask.
Greetings, Wolfgang
