Recently I came across with this question, “What all documents required for proper knowledge transfer of any Drupal Project"?

As usual I went to search on drupal.org but failed to find any document list so I started making it on my own.

So here is the list:

1. Information about Infrastructure: Server/Environmental Details (Dev/QA/Prod/)

2. Details of LAMP/WAMP Installations: Detailed info about Web server/DB/PHP

3. Other Application used on Servers: In case of Cache Server/Media server.

4. Details of Database server & Understanding of database structure: In case of cluster db servers, Details for Master, Slave db & replica db. In case of mixed storage engine list of table under specific particular storage engines.
