Thank you so much for the instructions.
I will deploy new windows server 2019 or 2022 and run the redmine 5.0.1 msi installer to deploy

current environment is Redmine 3.4.4 running on Windows server 2008 R2.

As you you mentioned the migration process.
Do you or Would you share the detailed steps or any link?

in this case ,i need to backup redmine installation, database and application files first .then restore to the new server.

Appreciate.

Hello Rony,

It is indeed complicated to set up a ruby environment on a Windows server. If you are successful, please follow the below documentation for an upgrade.

Doc: redmineupgrade

I strongly recommend you to go for a Linux option to save time and to have better stability and security.

Thanks, as we have run redmine in windows for a long time.
so we have deployed new server and instaled the redmine 5.0.3.

How can we export all the settings and attachments from old server redmine 3.4.3 to the new server redmine 5.0.3?

Hello,
I have upgraded Redmine many times and moved to another (Windows) machine too.

I used regular installation procedure with this deviation: Instead of initialization of the database with in initial values, I imported the old database (in your case the database for version3.4.4). I did this by dumping the old database to .sql file and after that executing this file on the newly created database. Right after successful import of the database a migration should be executed so as to make it in recent state as for Redmine 5.0.3.

Be careful about the plugins. Make Redmine upgrade without them, and search for their newer versions, compatible with Redmine 5.0.3.
