Resolution
- On the Filr 4 server, modify the /opt/novell/migration/migrate.load file to show as follows (note the highlighted portions):
- LOAD DATABASE
- from mysql://mysqluser:mysqlpass@localhost:3306/'mysqldb'
- into postgresql://pguser:pgpass@localpg:5432/'pgdb'
- SET MySQL PARAMETERS
- net_read_timeout = '5000',
- net_write_timeout = '5000'
- WITH create no tables, batch rows = 500, batch concurrency = 3, workers = 3
- ALTER SCHEMA 'mysqldb' RENAME TO 'public'
- EXCLUDING TABLE NAMES MATCHING 'ssqrtz_locks', 'databasechangelog', 'databasechangeloglock';
- After making these changes, follow these steps:
- Go to https://<ip or dns of the PostgreSQL appliance server>:9443
- Click the phpPgAdmin tile
- Click the PostgreSQL link (upper left)
- Provide the credentials: user name will be postgress
