Hello,

 

have a look to the docs e.g., here, and replace mysql with postgres:

 

https://kamailio.org/docs/tutorials/5.4.x/kamailio-install-guide-git/#create-mysql-database

 

There is a tool “kamdbctl” for it, you can also just use the plain scheme files in the kamailio source.

 

Cheers,

 

Henning

Hi Henning,

 

thank you for your reply.
Interesting approach.
Can you tell me where I can find information on how to "Install the new 5.4.x kamailio postgres DB"?

 

Cheers,

Giovanni

Hello Giovanni,

 

You are doing a bigger step in one upgrade. I would suggest the following approach to get the DB differences:

 

· Do a pg_dump -s for the database schema on the existing 4.4.x DB

· Install the new 5.4.x kamailio postgres DB on a test server etc..

· Do a pg_dump -s for the new database schema on the test server

· Compare the two schemas e.g. with diff or similar tool

· Use this to create an ALTER TABLE to (a copy) of the old database on a test server and test

· Alternatively you can of course also use other SQL techniques to insert the old data into the new one

 

Cheers,

 

Henning

Hi Dears,

 

I'm working on upgrading Kamailio from 4.4.6 to 5.4.0 in an installation where I use PostgreSQL

 

I understand that I have to upgrade in steps by following these links:
- http://www.kamailio.org/wiki/install/upgrade/4.4.x-to-5.0.0

 

in most of these links, in the section "Database", I find only the subsection "MySQL Database Structure", but I don't find the indications for DB migrations for PostgreSQL Database.

Only here https://www.kamailio.org/wiki/install/upgrade/5.2.x-to-5.3.0 I found both the subsection "MySQL Database Structure" and "PostgreSQL Database Structure".

 

What does this mean?

- that I'm getting lost in a glass of water?
- or that I don't have to make any changes to PostgreSQL?
- or that the queries to be launched on PostgreSQL are the same as those for MySQL? I would discard this hypothesis
- or that the wiki sections for PostgreSQL are missing? If this were the case, I could proceed with the update and then share the queries I launched to update the wiki.

 

thanks a lot

Giovanni Tommasini
