TestLink

Could anyone tell me how to upgrade testlink from 1.9.2 to 1.9.5?

I read section "5. Upgrade and Migration" in README file.

- Upgrade from 1.9.3 to 1.9.4/5
WARNING: if you are using a table prefix replace /*prefix*/ with your prefix
a) Execute install/sql/alter_tables/1.9.4/<your_db>/DB1.4/step1/db_schema_update.sql
b) Execute install/sql/alter_tables/1.9.4/<your_db>/DB.1.5/stepZ/z_final_step.sql

And, I also read in 1.9.3 release notes, seems the shema in 1.9.3 is the same as 1.9.2.

How can I execute the two commands above. I don't know how/why to replace the /*prefix*/ with my prefix. BTW, my database name is testlink.

Thank you in advance.

after I executed the two sql to my testlink database, and made the config_db.inc.php, the login.php is blank.

It must be buffer in browser. Now it works fine.
