This answer refers to the version in the original report. Check the controls and behavior in your own version.
Back up the old session and workspace, then open the new directory as a workspace. Start a new session with a brief handoff covering the current goal, changed files, unfinished work, and next step.
The original report describes a workspace path binding. If your build exposes a migration control, try it first with a disposable session. Reopen it and check its working directory. The host may still be writing live session files, so leave those files in place during testing.
