All,

Just as a follow-up, we were unable to figure out the exact cause of the 
missing dates of existence, but we believe it was an indexing error. Since the 
timing for the update prohibited us from running a re-index, we weren't able to 
confirm this. However, since many of the issues we've had in the past were 
solved with a re-index and no one else reported losing their data on this kind 
of jump, we feel reasonably confident in our assumption.

I apologize for causing a stir. It's a good reminder that running a re-index 
should be a part of our error checking process and we will update our upgrade 
and testing procedures to account for this in future upgrades.

Sincerely,

Corey

Subject: Agent Dates of Existence Lost to Update 2.8.1 to 3.1.1

Dear all,

Hello, this is Corey from the University of Georgia. We are testing an update 
to ArchivesSpace, going from version 2.8.1 to 3.1.1. During testing, we 
discovered that over 660 agent records lost their dates of existence 
information. Not all agents lost their dates of existence, however, with the 
vast majority migrating properly into 3.1.1. We are unsure why these agents in 
particular lost this info, but we know that the 3.0.0 release came out with two 
patches because of issues related to the dates of existence field (listserv 
email<http://lyralists.lyrasis.org/mailman/htdig/archivesspace_users_group/2021-June/008561.html>,
 JIRA 
ticket<https://archivesspace.atlassian.net/jira/software/c/projects/ANW/issues/ANW-1334>).
 Agents with range and single types are both affected.

Has anyone encountered this issue before? What might be the cause? For 
reference, I'm adding the JSON of an agent that lost their date of expression 
during the migration, as well as screenshots of what our agent records look 
like on 2.8.1 and 3.1.1:

  "dates_of_existence": [
    {
      "lock_version": 0,
      "begin": "1905",
      "end": "1983",
      "created_by": "cschmidt",
      "last_modified_by": "cschmidt",
      "create_time": "2021-02-23T14:45:47Z",
      "system_mtime": "2021-02-23T14:45:47Z",
      "user_mtime": "2021-02-23T14:45:47Z",
      "date_type": "range",
      "label": "existence",
      "jsonmodel_type": "date"
    }
  ],
Any help or info would be appreciated. Thanks.

Sincerely,

Corey
