Tip: Migrating Work Item URL Links

Summary

This tip applies to how RTC 3.x. work items can link to related artifacts or CLM resources such as test cases or requirements. These links are stored as absolute URLs in the RTC repository. If the target server is moved to a new address, these links become stale. For example: In RTC 3.0, the CQ Bridge was decommissioned, and these links need to be retargeted to the CQ server. This tip describes how to do that.

More Information

The functionality to rewrite Work item URL links is part of

• linkTypeId=<value>: The ID of the type of link to modify, for example
  com.ibm.team.workitem.linktype.relatedChangeManagement
  .

  The following link types are supported:

  Link Name	Target Application Type	Link Type Id
  Related Artifact	any location	com.ibm.team.workitem.linktype.relatedartifact
  Related Change Request	CM	com.ibm.team.workitem.linktype.relatedChangeManagement
  Affects Plan Item	CM	com.ibm.team.workitem.linktype.cm.affectsPlanItem
  Affected By Defect	CM	com.ibm.team.workitem.linktype.cm.affectedByDefect
  Tested By Test Case	QM	com.ibm.team.workitem.linktype.testedByTestCase
  Blocks Test Execution	QM	com.ibm.team.workitem.linktype.blocksTestExecutionRecord
  Affects Test Result	QM	com.ibm.team.workitem.linktype.affectsExecutionResult
  Related Test Case	QM	com.ibm.team.workitem.linktype.qm.relatedTestCase
  Related Test Execution Record	QM	com.ibm.team.workitem.linktype.qm.relatedExecutionRecord
  Related Test Plan	QM	com.ibm.team.workitem.linktype.qm.relatedTestPlan
  Affects Requirement	RM	com.ibm.team.workitem.linktype.rm.relatedRequirement
  Implements Requirement	RM	com.ibm.team.workitem.linktype.implementsRequirement
  Tracks Requirement	RM	com.ibm.team.workitem.linktype.rm.tracksRequirement
  Elaborated By Architecture Element	AM	com.ibm.team.workitem.linktype.am.elaboratedBy
  Change Sets	SCM	com.ibm.team.workitem.linktype.scm.tracksChanges

• find=<value>: A string inside of a URL to find and replace, for example
  https://<rtc-server>:<port>/jazz/oslc/cqrest/
• replace=<value>: The new string to replace the existing string, for example
  https://<cq-server>:<port>/cqweb/oslc/

Please note that this command will only rewrite the links themselves. References to URLs within work item descriptions or comments will not be replaced.

Example #1: Change web app root

The following command changes the webapp context root of the links from

  ./repotools-jazz.sh -modifyLinkURIs   	linkTypeId=com.ibm.team.workitem.linktype.relatedChangeManagement   	find=https://clmwb:9443/jazz /  	replace=https://clmwb:9443/ccm/  

The log will contain a detailed trace of the renaming operations performed:

Example #2: Change URLs from CQ Bridge to CQ

The following command shows the typical usage for migrating a CQ Bridge setup to a CLM/OSLC based one:

  ./repotools-jazz.sh -modifyLinkURIs   	linkTypeId=com.ibm.team.workitem.linktype.relatedChangeManagement  	find=http://rtc-server:port/jazz/oslc/cqrest/  	replace=http://cq-server:port/cqweb/oslc/
