What SLIM Does and Does Not Do¶
Being clear about the edges of the product prevents the two most expensive misunderstandings: assuming the output is verified, and assuming deployment is automatic.
What SLIM does¶
As noted previously, SLIM can:
Investigate and inventory existing integrations in Export files from live integration platforms, maximizing the value of your previous investments.
Create analysis documents detailing its findings for the Export file and for individual integrations to aid stakeholder understanding and integration evaluations.
Create a Functional Representation of the existing integration logic disconnected from both legacy integration platform and SnapLogic constructs.
Create SnapLogic expression libraries and pipelines to replace the discovered integration logic.
Perform tests on the logic included in the Functional Representation (Python) and SnapLogic incarnations of the integration.
Help you deploy the new assets into a SnapLogic organization.
Report on progress at every step of the modernization process.
Create an audit trail of documents to track decisions and behavioral equivalences - and divergence - through the modernization process.
What SLIM does not do¶
It is important to understand that while SLIM does a lot, there are certain tasks that it does not do.
It does not deploy anything to production automatically.
It does not test against your live systems.
It does not replace review by someone who knows the integration.
It does not decide what should be retired - it gives you what you need to decide that.
It does not replace the need for good corporate governance of your integration assets.
Decision-making must be owned by appropriate and identified individuals in your organization.
Output is generated, so output must be checked¶
As SLIM uses Export files from your existing integration platform, there may be contextual or non-encoded information held outside of the system that SLIM is not privy to which might alter analysis and modernization outcomes.
It is important that integration stakeholders - not necessarily only users of SLIM - review the produce outputs (analysis documents, etc.) for accuracy and completeness.
SLIM can and does identify components that are referenced by existing integrations that may be missing from the Export file, but it cannot identify unreferenced components that are not present.
Referenced omitted components are typically listed in the Export and Integration Analysis documents.
As these documents are the basis for the asset generation activities, it is important that these are checked for accuracy and completeness before progressing to subsequent steps.
NOTE: If you correct mistakes early, the process tends to be quicker and cheaper than waiting for the generation to complete and then rewriting the prompts to re-run the generation activities.
What the tests do and do not prove¶
When SLIM performs testing during the generation -> testing cycle it executes against an internal testing system using mock endpoints: it does not test against your environment.
The types of tests conducted by SLIM are:
Orchestration testing: verifies a parent / triggering integration pipeline successfully call a child / triggered pipeline.
Flow testing: verifies test data passing through the pipeline is processed in line with the logic noted in the Integration Analysis and Migration Plan documents.
Expression Library testing: verifies the expressions and algorithms within the shared Expression Library are processing data as documented in the Integration Analysis document. This applies only where an Expression Library was generated for the integration - not every integration needs one.
Every test has a Pass/Fail result: there is no in-between.
SLIM tests the logic of the generated pipelines; it does not test that they run successfully in your environment.
Successfully passing the tests within SLIM does not guarantee Production-readiness: validation in development, staging, and production environments remains your responsibility.
Known limitations at this release¶
There are some known limitations in SLIM.
August 2026:
No support for Single Sign-On (SSO) to the SnapLogic environment during the Platform Deploy stage. Credentials are entered directly.
No support for user-initiated password changes.
Users’ IP address(es) must be whitelisted for access to the SLIM environment.
Access to SLIM is dependent on users’ network firewall settings permitting HTTPS access to the SLIM tenant URL.
