One of the most critical operations which take place within an organization is data migration and any failure in this operation can turn out to be very catastrophic for the entire organization. A research conducted by Bloor says that around 60% of the data migration operations tend to fail. However, if 60% fail then what characteristics the rest 40% possess because of which they succeed? The reason behind this success is the 7 R’s.
The 7 R’s
It does not matter whether you are Prestashop user or not, compliance with the below mentioned 7 R’s will ensure success for you.
Resilient and Robust
Manage all areas of loading, data extraction, validation, transformation, and cleansing into the target and manage data of high volumes.
Reusable means the capability to reuse the migration components in other projects include data cleansing routines, transformation functions, and error handling.
Execute effectively and take absolute advantage of the target facilities to enable processing which is very much rapid in nature.
Reconciliation and Reporting
It means the provision of progress indicators during the migration process and reconciling of the process that has been completed.
The Key Steps
Data migration can be tricky typically when it comes to PrestaShop. The steps mentioned below are the key to success for you. If you follow the below-mentioned steps in latter and spirit then there are high chances that your data migration will be successful. The steps are as follows:
1. System Exploration
The first thing to do while migrating data is to explore and identify the source systems. The best way for this identification is product descriptions, group data, customer name, and addresses. Yes, there are various fields in the source PrestaShop website however not every one of them is applicable to the target PrestaShop website. You need to identify the data which is applicable and which is required for the migration. During the initial phase, if the majority of the sources do not contain the required data for the target model then this means that a gap has been identified. With Upgrade PrestaShop 1.6 to 1.7 free module, you just select the type of the data that you want to migrate. By these select, you can ignore the worry about redundancy or lack of the data from the source PrestaShop website. If such a scenario comes up then you need to get the data from multiple sources to develop a record with the right set of data in order to fulfill the target requirements. At the end of this stage, you will identify all the sources which are required for the target model.
The next step is to access the quality of the source data in PrestaShop site. In order to assess that it is recommended that you should go for data profiling. Data profiling is the procedure of systematically analyzing and scanning the contents of every column in the tables of interest. Profiling helps in the identification of data defects in the column level and at the table. Data profiling is very critical as far as data compliance and conformity is concerned. The three major advantages of data profiling are:
- Through data profiling, you can quickly identify whether your data is compatible with your business purpose
- Through profiling, you can perfectly plan the strategy of integration
- Finally, it helps in the successful integration of the source data
The next thing which you need to do is to go for the migration design. During this phase, you need to define the design and technical architecture of the migration process. Moreover, you will also define the process of testing. During this stage, it is necessary that you put your plans for next 4 steps on a piece of paper. The plan will include your technical details, your timelines, and any other concerns. The point is that the entire project needs to be documented.
Do not go for a just enough development approach as far as your data migration is concerned. first of all, you need to subset the data and test one category at a time. In case your project is large then in such a scenario you can test and develop each category in parallel. In order to ensure data cleansing routines, mappings and transformations, begin by checking each component individually in subsets which are small. Finally, enhance the data volumes and link all the components together into a migration job which is single.
Now it is the time to run the migration. In order to execute the migration, the website URL of source PrestaShop website should be available while migrating the data so please don’t delete or remove your current site before completing the migration. Data synchronization technology is also required to catch any changes that may take place during the initial load.
Your current theme and modules can NOT be migrated, the new site should use another theme which is compatible with the latest version of PrestaShop.
When you use Upgrade PrestaShop 1.6 to 1.7, you can choose a part or all of the data on the source to migrate to the target PrestaShop website. It’s great, right?
Once the data has been migrated you need to decide when to transfer it to the new system. During the execution stage, logs and audit trails are developed to ensure that all data has been migrated correctly. After reviewing the logs and the audit trails, you can make the decision regarding the transition of the users to the new system.
A systematic retirement policy is developed to address the system which is old. Since not all the source systems will be retired hence there are high chances that data quality problems may be identified and may also require rectifying. You also need to monitor the data quality and ongoing improvements to the new system.
