Upgrading from 1.3.8 to 1.4.11

[rcubeuser]

I was  upgrading today my roundcube with:

sudo ./bin/installto.sh <target_dir>

And at the end I have this output:

Executing database schema update.
ERROR: Error in DDL upgrade 2018021600: [1050] Table 'filestore' already exists
Updating database schema (2018021600)... [FAILED]
All done.

I found a possible solution: https://forum.iredmail.org/topic17699-roundcube-1410-upgrade-fails-table-filestore-already-exists.html

And I want to know if this solves this issue

P.S. i'm not using iredmail, just a basic postfix/dovecot configuration

Well, there was a pre-installed script used by me that already did this updrade, sorry for my confusion.
