- This tool can be used to convert an existing (foreign) wiki database with
- all its pages to the ewiki database and page format. It is very experimental
- and you should consider using the export utility of your previous Wiki with
- <tt>ewikictl</tt> afterwards to reimport it here.
-
- <br>
- <small>
- <br>
- Some of the databases you can export from need more parameters, and if you
- transfer data from one SQL-based database scheme to another, you need to
- have source and target tables in the same database (cannot cross-convert
- from/to different servers/dbms). And the target tables for foreign schemes
- must already exist.
-
- <br>
- <br>
- You must have your target ewiki database and plugin already defined
- in your <tt>config.php</tt>. If you want a special target, then you must
- edit <i>this</i> script (<tt title="<?php echo __FILE__; ?>">t_convertdb.php</tt>)
- and uncomment the other targets and insert correct define() or assignment
- statements to make it work yourself.

- <u>notes</u>
- <br>
- - If you access the '<b>configured $ewiki_db</b>' then you do not need to
- set any option, because this refers to whatever you configured in your
- 'config.php' script as default database. Always the best option.
- <br>
- - For <b>PmWiki</b> you must set the 'subwiki identifier' (to "Main" at best), so
- the conversion utility can extract one of the database fragments. You
- also need to define the 'file/directory' setting to the exact position
- of PmWikis 'wiki.d' or 'wikilib.d' data dirs (relative to the ewiki
- installations base directory; and separate multiple dir names using
- spaces, commas or colons).
