Step 2 (Option 3). Requires Poppy CSP #3. Unstable on big amounts of data

Run time:

After upgrade, before reindex

Precondition:

No preconditions

Action

Run script:

-- Change search path for the script
SET search_path = <tenant>_mod_inventory_storage;

-- Recalculate effective values for items with no call number type specified. No shelving order recalculation
UPDATE item
SET jsonb = set_item_effective_values_no_shelv_recalc(item_data.holdings, item_data.item)
FROM (
    select item.id, hr.jsonb as holdings, item.jsonb as item from holdings_record hr
    join item on item.holdingsRecordId = hr.id
    where trim2null(hr.jsonb->>'callNumberTypeId') IS NOT NULL
    and trim2null(item.jsonb->'effectiveCallNumberComponents'->>'typeId') IS NULL
) AS item_data
WHERE item.id = item_data.id;

Step 3. Requires Poppy CSP #3. Unstable on big amounts of data

Run async item shelving order migration via api. Anytime, may be during runtime. Values surrounded by "<>" to be replaced

curl --location --request POST '<okapi-url>/inventory-storage/migrations/jobs' \
--header 'X-Okapi-Tenant: <tenant>' \
--header 'X-Okapi-Token: <token>' \
--header 'Content-Type: application/json' \
--data '{
  "migrations": ["itemShelvingOrderMigration"],
  "affectedEntities": ["ITEM"]
}'

Monitor execution until response body parameter "jobStatus" is "Completed". <jobId> is returned from previous request as "id" parameter in response body

curl --location --request GET '<okapi-url>/inventory-storage/migrations/jobs/<jobId>' \
--header 'X-Okapi-Tenant: <tenant>' \
--header 'X-Okapi-Token: <token>' \
--header 'Content-Type: application/json'

Once migration is completed - reindex instances
