Just to add - copying the mythconverg files alone will require adding the
mythtv user again/granting privileges, as that data is stored in the main
mysql database tables, AFAIK.
The DB initialisation file at /usr/share/mythtv/sql/mc.sql on my 0.28
MythTV system does the following:
GRANT ALL ON mythconverg.* TO mythtv at localhost IDENTIFIED BY "password";
GRANT CREATE TEMPORARY TABLES ON mythconverg.* TO mythtv at localhost
IDENTIFIED BY "password";
You can run the above SQL statements from the command line using the mysql
client. You can obtain the password for your old system from the MythTV
config.xml file and replace it in the statements above as necessary.
