Enterprises Aggressively Moving Legacy Systems to Cloud, Shows Study


Companies are moving legacy systems to the cloud faster than ever, according to a new global survey.

The survey commissioned by software services provider Lemongrass said that enterprises are moving legacy resources in order to secure their data, despite the challenges that arise from cloud migration and adoption.

Some 77% of IT leaders said their primary motivation for migrating legacy systems to cloud infrastructure was either a desire to secure data, maintain data access or save money, a new survey finds. Optimizing storage resources and accelerating digital transformation were other top reasons, according to the survey.

Security, People, Process & Cost Complicate Cloud Migrations

Considering the importance of data security, it’s no surprise that security and compliance were listed by 59% of IT leaders as the top challenge facing enterprises when moving legacy systems to the cloud. Meanwhile, 43% of respondents said migrations took too long, 38% said costs were too high, and 33% said a lack of in-house skills was the top complicating factor.

Regarding cost, 69% of respondents said the typical legacy-to-cloud migration cost between $100,000 and $250,000, and 57% of respondents said that somewhat or very rarely do these projects come in under budget. In terms of job skills, database integration experience was cited by 21% of respondents as the top skill required for performing legacy migrations, followed by experience with the chosen cloud platform (15%), previous migration experience (12%) and testing validation (also 12%). 68% of respondents said it was very or somewhat hard to find people with these skills, and 40% said migrations took at least seven months to complete.

Employee Training & Data Security Are the Top Operating Challenges 

42% of survey respondents said that difficulty training end users was the top challenge to using legacy systems now running on cloud infrastructure. 40% said the top challenge was that security concerns had not been adequately addressed, 34% said the cloud platforms they had chosen did not work as expected, and another 34% said the top challenge to running legacy systems in the cloud was a lack of in-house skills. Meanwhile, 50% said the top skill was database management, and 48% said programming. 71% of respondents said it was hard or somewhat hard to find these people.

Lessons Learned: Migrating & Running Legacy Systems in Cloud

The top three lessons learned when migrating legacy systems to the cloud were 1) allow for sufficient time (54%); 2) dedicate sufficient financial and people resources (52%); and 3) ensure you have the correct people/skills in-house (52%). The top three lessons learned when running legacy systems on cloud infrastructure were 1) allow for sufficient time to manage the application (53%); 2) ensure you have the correct people/skills in-house (52%); and 3) ensure you achieve the outlined business goals (46%).

Vince Lubsey, CTO at Lemongrass said, “Enterprises are anxious to reap the benefits of moving legacy systems to the cloud. They understand there are challenges but the benefits far outweigh the obstacles.”

“The key to success is following best practices, proper training and time management. It also helps to have the guidance of an experienced partner to create the required cloud operating model,” he said.
