## What is TFS4JIRA synchronizer

Synchronizer is a web application accompanying Jira plugin. It is required for the data to be properly transferred between the systems and is required regardless if you are using a cloud or on-premises versions of TFS / Azure DevOps and Jira.

> ℹ️ If you are using check-ins synchronization and you are using Jira Cloud, you need to make the Synchronizer web interface available from the Internet. Please refer to [Settings for Jira Cloud](https://appfire.atlassian.net/wiki/spaces/TFS4JIRA/pages/1656127753) for more details.

  
**TFS4JIRA Synchronizer** application can be installed on any server machine that has network access to both Jira and TFS / Azure DevOps and which is always online.

You can [download installer from here](https://apps.appf.re/t4j/web/product).

**TFS4JIRA Synchronizer** installation process is quite straightforward. Simply run the installer **as an administrator** and follow instructions. The installer will warn you if any of the required components is missing.

> ℹ️ **TFS4JIRA Synchronizer** application will be created under site named "<span style="color: #222222">Default Web Site" - if this site doesn't exist then </span>installation process will fail. If you really need to install the synchronizer on a different web site, or if your site is called differently, you will need to use the command line to invoke MS installer with some additional parameters, like this:
> ℹ️ 
> ℹ️ `    Appfire.Synchronizer.Installer-x.y.z.exe /i WEBSITENAME="example" WEBSITEPORT=99`
> ℹ️ 
> ℹ️ where WEBSITENAME is the name of your **existing** web site, under which you want to install the synchronizer, and WEBSITEPORT is its port - <u>both of these options must be specified</u>, otherwise the result is undefined.
> ℹ️ 
> ℹ️ Also you can add INSTALLLOCATION="c:\yourpath" parameter to install Synchronizer in different folder.
> ℹ️ 
> ℹ️ - If you have a different **Physical Path **than the default path (%SystemDrive%\inetpub\wwwroot) for your site, then you will need to specify the INSTALLLOCATION by adding this parameter.
> ℹ️ 
> ℹ️ Additionally, you can install TFS4JIRA using the following switches:
> ℹ️ 
> ℹ️ - /quiet - displays no UI whatsoever
> ℹ️ - /passive - displays a UI but requires no user input. Essentially just displays an install progress bar

You should be able to access the installed application under the following URL: ***http://<your-iis-host-name>/tfs-jira-synchronizer***.   
In order to log in to the application just use administrator's login and password.
