Migration to new platform might be needed but sometimes it’s bring some challenges which can be taken care if you are dealing with web experts.

Few challenges

• Data Migration
• Duplicate Content
• Hosting
• URL Linking
• Backup Plan

Data Migration:

• Password Encryption issue : New platform might not be using same algo to encrypt password as old platform, either identify the old algo logic or ask users to create new password in decent manner
• Image issues: It might be possible that new platform use different size of images or number of images, one need to look into that also
• History: It’s difficult to migrate order history because of various relations, it might give a very bad impression on user if he wake up and see all his rewards points are gone

Duplicate content:

If canonical URLs are not properly set after migration, there will be lots of duplicate content issue. One can use tools for this or can go manual way

Hosting:

If proper hosting and caching not implemented on server prior to migration, you end up with downtime, If you have large traffic on your website, implementing varnish, memcache is very important

URL LINKING:

Some of your URL might be having good page rank and authority, either use same URL for products or use 301 Redirect URL, it informs Google and other search engines that the requested URL has permanently moved to another

Backup plan

Be ready to use old platform in case of any challenges, don’t trash old platform for at least 3 months.
