  Warnings:

  - You are about to drop the column `documentMetaId` on the `Document` table. All the data in the column will be lost.
  - You are about to drop the column `customEmailBody` on the `DocumentMeta` table. All the data in the column will be lost.
  - You are about to drop the column `customEmailSubject` on the `DocumentMeta` table. All the data in the column will be lost.
  - A unique constraint covering the columns `[documentId]` on the table `DocumentMeta` will be added. If there are existing duplicate values, this will fail.
  - Added the required column `documentId` to the `DocumentMeta` table without a default value. This is not possible if the table is not empty.
