An embodiment operates by extracting a resource snapshot into memory. The resource snapshot is formatted in a first configuration. An embodiment performs a transformation on the resource snapshot, thereby transforming the resource snapshot from the first configuration to a second configuration for an environment into which the resource snapshot is being restored. The transformation is made up of a set of operations. One of the operations includes a regular expression. Once the transformation is complete, the resource snapshot is restored to the environment based on the second configuration. ## Claims ### Claim 1 A method for restoring an application, comprising: extracting, by a processor, a resource snapshot into a memory, wherein the resource snapshot is a hierarchical structure in textual form that specifies a first resource configuration indicating where portions of the application are accessed in a first cloud environment; performing, by the processor, a transformation, comprising a set of Modified JavaScript Object Notation (JSON) Patch operations, on the resource snapshot, thereby transforming the resource snapshot from the first resource configuration to a second resource configuration indicating where portions of the application are accessed in a second cloud environment, wherein performing the transformation comprises performing each Modified JSON Patch operation from the set of Modified JSON Patch operations in sequence, and wherein performing a Modified JSON Patch operation from the set of Modified JSON Patch operations comprises: selecting, using a regular expression, a plurality of strings in a path in the resource snapshot or a plurality of values in the path in the resource snapshot as a capture group; and applying the Modified JSON Patch operation to the resource snapshot using the capture group; and restoring, by the processor, the application to the second cloud environment based on the transformed resource snapshot specifying the second resource configuration. ### Claim 2 (depends on 1) The method of claim 1, further comprising: determining, by the processor, that performance of the transformation succeeded; and wherein restoring the application to the second cloud environment comprises restoring the application to the second cloud environment in response to determining that the performance of the transformation succeeded. ### Claim 3 (depends on 2) The method of claim 2, wherein determining that the performance of the transformation succeeded comprises determining, using at least one test operation, that the resource snapshot is formatted in the second resource configuration. ### Claim 4 (depends on 1) The method of claim 1, wherein another Modified JSON Patch operation from the set of Modified JSON Patch operations in the transformation includes a path reference or a value reference with a wildcard character. ### Claim 5 (depends on 1) The method of claim 1, further comprising: receiving, by the processor, a selection of the second cloud environment; detecting, by the processor, the second resource configuration for the second cloud environment; and outputting, by the processor, a description of the second resource configuration to a user. ### Claim 6 (depends on 5) The method of claim 5, wherein detecting the second resource configuration comprises detecting, using at least one test operation, one or more paths of the second resource configuration in the second cloud environment. ### Claim 7 (depends on 1) The method of claim 1, further comprising: receiving, by the processor, a selection of the second cloud environment; detecting, by the processor, the second resource configuration for the second cloud environment; and selecting, by the processor, the transformation based on the second resource configuration. ### Claim 8 (depends on 7) The method of claim 7, wherein detecting the second resource configuration comprises detecting, using at least one test operation, one or more paths of the second resource configuration in the second cloud environment. ### Claim 9 A system, comprising: a processor; and a memory communicatively coupled to the processor, wherein the memory stores instructions configured to, when executed, cause the processor to: extract a resource snapshot into the memory, wherein the resource snapshot is a hierarchical structure in textual form that specifies a first resource configuration indicating where portions of the application are accessed in a first cloud environment; perform a transformation comprising a set of Modified JavaScript Object Notation (JSON) Patch operations on the resource snapshot, thereby transforming the resource snapshot from the first resource configuration to a second resource configuration indicating where portions of the application are accessed in a second cloud environment, wherein performing the transformation comprises performing each Modified JSON Patch operation from the set of Modified JSON Patch operations in sequence, and wherein performing a Modified JSON Patch operation from the set of Modified JSON Patch operations comprises: selecting, using a regular expression, a plurality of strings in a path in the resource snapshot or a plurality of values in the path in the resource snapshot as a capture group; and applying the Modified JSON Patch operation to the resource snapshot using the capture group; and restore the application to the second cloud environment based on the transformed resource snapshot specifying the second resource configuration. ### Claim 10 (depends on 9) The system of claim 9, wherein the instructions are further configured to: determine that performance of the transformation succeeded;
