This file gives you instructions on how to migrate from one version of
OpenDNSSEC to another.

*** Migrating from 1.4.X to 1.4.8 ***

As of 1.4.8 the database has changes slightly. To migrate between databases
run the SQL statements given in:

    enforcer/utils/migrate_1_4_8.sqlite3
  or
    enforcer/utils/migrate_1_4_8.mysql

  against your existing database.

*** Fix for MySQL zone delete issue ***

  As reported in:
    https://issues.opendnssec.org/browse/OPENDNSSEC-338

  This effects MySQL databases created after 1.4.0a3 or 1.3.9 where zone deletion was changed.

  If you wish to fix this without losing any existing information then run the sql statements
  given in:

    enforcer/utils/migrate_zone_delete.mysql

  against your database.

  Note that sqlite is not effected as we do not enforce any constraints.


*** Migrating from 1.3 to trunk/1.4 ***

  r5914 has some kasp database changes to allow for an update to the zonelist.xml schema. 
  This means that if you want to use this version or any after it with a database created 
  earlier you will need to do one of 2 things...

  1) wipe and recreate your kasp database (run ods-ksmutl setup) which will lose all of 
     your current state.
  
  If you need to keep your key information then,

  2) run the sql statements given in:

     enforcer/utils/migrate_adapters_1.mysql
  or
     enforcer/utils/migrate_adapters_1.sqlite3

  against your existing database.

  These changes allow flexibility in the input and output adapters.


*** Migrating from v1.2 to v1.3 ***
 
  There are no migration scripts to run to make this transition.


*** Migrating from v1.1 to v1.2 ***

  There is a kasp schema change from the 1.1 branch (or trunk if you built
  prior to r3823). To make this transition you have 2 options:

  1) Run ods-ksmutil setup again. This will remove _all_ the current
  information from the kasp database and start you off again with a fresh
  environment.

  If that is not an option, or you want to try something else then:

  2) run one of the migration scripts
        enforcer/utils/migrate_keyshare_mysql.pl
  or
        enforcer/utils/migrate_keyshare_sqlite3.pl
  depending on your database.

  NOTE: Although these scripts have been tested it is recommended to make a
        backup of your database prior to running them.


*** Migrating to a larger keypairs(id) field (MySQL ONLY) ***

  The version of the MySQL database that was created with v1.2 (and prior to
  svn r4465) had a smallint datatype for the keypairs(id) field. This limits
  the number of keys that the system can store to 32767.

  If this number is not large enough then the script:

  enforcer/utils/migrate_id_mysql.pl

  will increase it to an int, which can store 2147483647 keys.

  NOTES: Although this scripts have been tested it is recommended to make a
         backup of your database prior to running them.

         This issue only applies to MySQL backends.


*** Migrating between SQLite <=> MySQL (same OpenDNSSEC version) ***

  convert_database.pl located in enforcer/utils can be used to convert
  between SQLite and MySQL on the same OpenDNSSEC version. If you wish to
  convert to another OpenDNSSEC version you need to migrate existing
  database to that version first.

  NOTE: You must create the MySQL database and database user manually
        before converting to MySQL.

  Convert from SQLite to MySQL example:
  enforcer/utils/convert_database.pl \
    --from dbi:SQLite:dbname=/var/opendnssec/kasp.db \
    --to dbi:mysql:database=kasp;host=localhost \
    --to-username <username> --to-password <password>

  Convert from MySQL to SQLite example:
  enforcer/utils/convert_database.pl \
    --from dbi:mysql:database=kasp;host=localhost \
    --from-username <username> --from-password <password> \
    --to dbi:SQLite:dbname=/var/opendnssec/kasp.db
