|
|
This script help you migrate from a pre-1.7 database to 1.7 and later\n
|
|
It is important to note, that this script only touches the 'calendarobjects'
|
|
table.
|
|
|
|
If you do not have this table, or don't use the default PDO CalDAV backend
|
|
it's pointless to run this script.
|
|
|
|
Keep in mind that some processing will be done on every single record of this
|
|
table and in addition, ALTER TABLE commands will be executed.
|
|
If you have a large calendarobjects table, this may mean that this process
|
|
takes a while.
|
|
|
|
Usage:
|
|
|
|
{$argv[0]} [pdo-dsn] [username] [password]
|
|
|
|
For example:
|
|
|
|
{$argv[0]} mysql:host=localhost;dbname=sabredav root password
|
|
{$argv[0]} sqlite:data/sabredav.db
|
|
|
|
