Hi,

you need to follow all upgrading steps:

2.3.6 -> 2.4.latest
2.4.latest -> 3.0.latest
3.0.latest -> 3.1.latest
3.1.latest -> 3.2.latest
3.2.latest -> 3.3.latest
3.3.latest -> 4.0.latest
4.0.latest -> 5.0.latest

For each of the migrations you have to follow the instructions in the UPGRADING file of the target version (which points to the manual in newer versions)

Things you might need to do:
- convert database to utf-8
- change database storage engine to innodb
- migrate ACLs to the database

Also you need to switch to a newer operating system and a newer version of the database if you are still running on the original setup.

I strongly suggest to get professional support for this kind of task as deeper OTRS knowledge is needed to solve potential issues!

Thanks for your quick reply, Shall I make a clone and try to update, it affects the live otrs running?

[jojo]

a clone is suggested for testing of the whole procedure.

For live migration you need to stop the running instance first as no changes are allowed during upgrade

Thanks, I will try with clone one, Please explain me How can I make the clone in same server, I copied all the files from otrs 2.3.6 to new test location, and copy the DB create a new DB also, I changed the required changes in kernal/config.pm also, But clone site is not working, it shows this error 'The requested URL /otrs/bin/cgi-bin/index.pl was not found on this server.'. What I must change Please explain Me. Thanks in advance.

you shpuld use a different server as newer versions will not run on old PERL versions. Also webinterface is not needed for the migration steps

[magnetmo]

Thanks, Different server is not possible, I will try update from existing system,

2.3.6 -> 2.4.latest
2.4.latest -> 3.0.latest
3.0.latest -> 3.1.latest
3.1.latest -> 3.2.latest
3.2.latest -> 3.3.latest
3.3.latest -> 4.0.latest
4.0.latest -> 5.0.latest

following this system, Any documents to follow this procedure, Because am not well in Terminal command execution also.

for this task you need good skills in linux and database administration. Please read the UPGRADING (and also the INSTALL) file for each target version before starting any migration attempt.

You shoud hire an expert before destroying the installation...

I got only these two documents, I does not get documents for remaining versions. if you have please send URL. Thanks.

UPGRADING documentation is in the root of each release folder until the documentation starts being on the github site.

I tried to update from 2.3.6 to 2.4.15 after Update when I open URL in browser it throw this error
Forbidden

You don't have permission to access /otrs/bin/cgi-bin/index.pl on this server.

please help me to fix this.

[jojo]

as I said beofre you need to read and understand the UPGRADING and INSTALL files

to make a long story short: hire some professional help, a migration this size needs deeper OTRS and linux knowledge.

I have followed the documents from UPGRADING file, What is the mistake, may be Permission Problem?
