Strategies For A Successful Data Platform Migration
Data Engineering Podcast
How to Prevent the Need for Migrations
I think sometimes the tooling is almost serving the opposite effect of locking you further into what you're currently on. The more we start to use the features that are specific to that platform the harder ever moving away from it will be right. We got really obsessed with the ability to use connected sheets and have G seats basically be a very simple interface for our analysts to do mappings of data and things like that. If you're not careful you start leaning too far into a vendor specific feature set you make yourself very tightly coupled to things that are Specific to That Vendor.

Summary
All software systems are in a constant state of evolution. This makes it impossible to select a truly future-proof technology stack for your data platform, making an eventual migration inevitable. In this episode Gleb Mezhanskiy and Rob Goretsky share their experiences leading various data platform migrations, and the hard-won lessons that they learned so that you don't have to.

- Your host is Tobias Macey and today I'm interviewing Gleb Mezhanskiy and Rob Goretsky about when and how to think about migrating your data stack
Interview
- Introduction
- How did you get involved in the area of data management?
- A migration can be anything from a minor task to a major undertaking. Can you start by describing what constitutes a migration for the purposes of this conversation?
- Is it possible to completely avoid having to invest in a migration?
- What are the signals that point to the need for a migration?
- What are some of the sources of cost that need to be accounted for when considering a migration? (both in terms of doing one, and the costs of not doing one)
- What are some signals that a migration is not the right solution for a perceived problem?
- Once the decision has been made that a migration is necessary, what are the questions that the team should be asking to determine the technologies to move to and the sequencing of execution?
- What are the preceding tasks that should be completed before starting the migration to ensure there is no breakage downstream of the changing component(s)?
- What are some of the ways that a migration effort might fail?
- What are the major pitfalls that teams need to be aware of as they work through a data platform migration?
- What are the opportunities for automation during the migration process?
- What are the most interesting, innovative, or unexpected ways that you have seen teams approach a platform migration?
- What are the most interesting, unexpected, or challenging lessons that you have learned while working on data platform migrations?
- What are some ways that the technologies and patterns that we use can be evolved to reduce the cost/impact/need for migraitons?
