(as a followup to phab:T862#20463)
We say in Phabricator/Help#Claiming_your_previous_Bugzilla_and_RT_accounts:
Your account activity (comments, reports you created, etc) will be merged into your Phabricator account within the next days. Please be patient as this can take quite some time, depending on how active you were in Bugzilla and RT before. After the process to link your previous, imported contributions to your Phabricator account has finished, you will be e.g. able to search for reports in Phabricator that you had created in Bugzilla before Bugzilla's reports were imported into Phabricator.
What happens if I won't claim my Bugzilla account "within the next days" (timeline does not list that)? I think we cannot reasonable except that even majority of volunteers migrates "within the next days". Need more clarification on the migration process itself and we can inform users better. ~~~~
