Develop Magento Module "Migrator"

**Develop Magento Module "Migrator"** We need to migrate data from a system to Magento 2. We work in stages. If the result after one stage is satisfactory for us, we will start with the next stage. We prefer a long-term cooperation b2b. We have a tight schedule. We need to move fast. It must be developed according to Magento 2 dev guide. [login to view URL] **stage 1** ========= **Setup Install Schema** Table "wly_migration_ordertable" Table "wly_migration_orderitem" Table "wly_migration_file" You will receive a database schema as a sql file. **Data Import** One time import of user data by sql-File direct to database. No php Importer required. I will do this one-time import by meself. You will receive a sql test file with dummy data for testing. **Plugin** like [login to view URL], but this module do not work with Magento 2.2.3. The goal of this Plugin is to maintain user login from old platform to the new magento 2 shop. Users must be able to log in to the new Magento Shop with the same login as on the old platform. On the old platform, passwords as a simple md5 hash. See this code: [login to view URL] **view/template** Extended Template for user account and show below the order history the migrated data from table wly_migration_ordertable. An order from this table has multiple orderitems. Each of these orderitems can have files. The migrated orders cannot be reordered. We offer the data for information only. There is no functionality for the customer in this table. No design needed. We only need a html table with the content. **stage 2** ========= **remote file download controller** The customer can download all files. When clicking on "Download" javascript will make an ajax request to the Magento Shop. The Magentoshop then returns the file. The file is located on a remote server that is not publicly accessible - only for IPs on the whitelist. **stage 3** ========= **import vouchers/coupon codes** one-time migrate voucher database to magento 2 coupons by php script. Two source tables are avaible as csv file. source schema: table "voucher" id name code percent (1/0) value maxcount count maxdate 3 Coupon 161001 0 100.00 1 1 NULL code => code for customer to input in cart maxdate => expiration_date count/maxdate: only import voucher and voucher_rule if count < maxcount count => times_used maxcount => usage_limit value => discount_amount There are vouchers for products and vouchers for carts. table "voucher_rule" id rule_id group_id product_id template_id topic_id subtopic_id position invert discriminator w2p typ comparator value 23 2182 NULL 1014 NULL NULL NULL 1 0 voucherruleproduct NULL NULL NULL NULL
