      <p><strong>Note</strong>: These field limit updates for E2B were added in Vault Safety 22R1 (April 2022). Veeva intends to automate the transition of data from the legacy fields to the new longer fields in 22R2 (August 2022). If you are concerned about hitting the field length limits, you may contact support to enable the new fields now. If the fields are enabled before 22R2, you can manually move the data or use Vault Loader. With the 22R2 release, this process will be automatic.</p>
