How to convert sqlite2 to sqlite3 and what are the differences between both versions?

Question

I need to convert from sqlite2 db to sqlite3, is there any tutorial that shows how to do it? And if I migrate correctly what to expect as I start the project?

Answer 1

EDITED: ANSWER TO THE QUESTION

To the conversion

1. Go to http://www.sqlite.org/download.html
2. Download sqlite-dll file (which stays in Precompiled Binaries For Windows)
3. Unpack it and copy to C:\Windows\System32 folder

What are the differences? (quoted from PHP - SQLite vs SQLite3)

1. SQLite2 internally stores every value as a string, regardless of its type.
2. Upgrading to SQLite3 will certainly shrink the database size since numbers and BLOBS get stored in their native formats, which could make things run faster.
3. starting from 3.6.23 version it supports foreign keys.
