While migrating applications to the cloud, IT teams have to deal with certain unique challenges which they might not have anticipated. Especially with applications which are quite old or have been in use for a decade or long, there are certain complex issues to be resolved while migration to the cloud.
Some of the most common issues faced include:
- Availability of the software to be installed: While porting older third party software components on to the cloud, the biggest concern remains the availability of the software to be installed on the cloud. It might be quite possible that the vendor has stopped selling that particular version of the software which was available years ago. In such cases the client is faced by the dilemma of whether to pay extra to upgrade the software version or shelve off their plans to migrate it to the cloud.
- OS compatibility: Since older applications keep running on the same operating system versions they were first installed in, the IT team needs to find the IaaS provider that will let them run the application on the older OS. This might not always be possible. The IaaS provider might not support the older OS and may insist on running the application on the newer OS.Such a scenario where the application is forced to run on a newer OS, requires thorough testing of the application to ensure that no new bugs or issues arise.
- Database issues: This is yet another issue that the migration process may have to resolve. Migrating applications would also involve transfer of server based databases like SQL server and it is important that we try not to change the version or type of the database. Any change would require rigorous testing to ensure that the application works well with the changed database without any new issues.
