Content DB Migration

Background:

Problem Statement :

For existing users, already content DB is created so, categories filed will not be there and we are using content.category1 so, it will throw undefined error

Key Design Problem:

Update content DB keys BMGS to category1, category2, category3 and category4. The new DB will be created for new user with category1,….category4 but for existing user we have to write a migrate code for DB update with category[i]

export interface Content {
    .....
    subject: string | string[];
    board: string;
    medium: string | string[];
    gradeLevel: string[],
    ......
}

export interface Content {
    category1: string | string[];
    category2: string | string[];
    category3: string | string[],
    category4: string | string[];
    ..........
}
