被 youtrack 虐过几次，对它有一点不怀好感。。。其实主要了解了它的数据库以后也就好多了，安装的时候一定要先把数据库位置安排好了，便于日后维护。如果忘记数据库在哪里了，那也可以在这个地方找到：c:\ProgramData\JetBrains\YouTrack\conf\internal\wizard-configured.properties

今天是因为要转移 youtrack 了，所以在网上查了一下怎么把一台机器上的 youtrack 数据导入到另一台上。（参见 Import from Another YouTrack Server - YouTrack 6.x Documentation - Confluence）

To import all issues in a project from one YouTrack server to another:

  1. Download the latest version of YouTrack’s Python Client Library and unzip it.
  2. Ensure that either Python is installed in your system.
  3. Execute the following command:
1
python youtrack2youtrack.py source_url source_login source_password target_url target_login target_password projectId

The following command-line parameters should be provided:

Parameter Description
source_url An URL to a source YouTrack server you want to import issues from.
source_login Username to log in to a source YouTrack server.
source_password Password to log in to the source YouTrack server.
target_url An URL to a target YouTrack server you want to import issues to.
target_login Username to log into the target YouTrack server.
target_password Password to log in to the target YouTrack server.
projectId projectID of a project you want to import to the target YouTrack server.
