Prior to a record being imported from OCLC, the OCLC tcn is in the 001. If you have the Global setting "Maintain 001-003-035 according MARC" set to true, then the OCLC tcn will be transferred to 035s (one with the ocm/ocn prefix and one without) and a locally assigned record id number will be in the 001. The 003 will be or local control number identifier for the 001 (from https://www.loc.gov/marc/bibliographic/ecbdorg.html). Since PINES has this set for true, I am not sure what the behavior is for false, other than that the locally assigned 001 becomes the record TCN in your database. I don't know what happens to the OCLC tcn -- it may be retained in an 035.
Both the 001 and the 035 are system supplied. The 001 is not editable -- attempts to edit will add an additional 035 while retaining the system supplied 001. If all your records are from OCLC, and the flag set to true, then all your records should have an 035 with the OCLC tcn. If you have the global flag set to true, for those records imported since you migrated to Evergreen, you will likely have two 035s, such as: 035 ‡a(OCoLC)ocn276335043 035 ‡a(OCoLC)276335043 J.
