+# Migrating to gist v13.0 from v12.0
+
+This file gives a quick overview of using the migration utilities provided
+by the gist team to help migrate from the previous version of gist.
+
+> See also additional documentation in the [Major Version Migration](../../docs/MajorVersionMigration.md).
+
+## Important Remarks
+
+- **These scripts are not cumulative; you must run the migrations for each version of gist
+  in sequence.**
+
+- **These utilities are a starting point.** You should review them before running
+  them to make sure you approve of the actions prior to using them.
+
+- **These utilities do not handle everything**, in some cases we can only warn you
+  about changes that were made in gist and you will need to decide how you want
+  to handle the changes.
+
+## Migration Queries
+
+All of our migration tools are SPARQL queries.
+
+The following directory structure holds the migration scripts:
+
+    .
+    └── queries/
+        │
+        ├── action/
+        │   ├── default/
+        │   │   └── *.rq
+        │   └── ngraphs/
+        │       └── *.rq
+        │
+        ├── report/
+        │   ├── default/
+        │   │   └── *.rq
+        │   └── ngraphs/
+        │       └── *.rq
+        │
+        └── uom_queries/
+            └── *.rq
+
+The `./queries/` directory contains the following directories:
+
+- `./queries/action/` : Update queries for migrating from Gist v12.0 to v13.0
+
+- `./queries/report/` : Validation queries that return SHACL validation reports for data that does not comply with Gist v13.0
+
+- `./queries/uom_queries/` : Queries for migrating to the new ontology for magnitudes, aspects, and units of measure
+
+The action and report directories each contain the following two directories:
+
+- `default/` : These queries only work on the default graph`*`
+
+  > `*` the handling of these queries will be dependent upon which triplestore you are using and how it was configured. Some triplestores will only use
+  > triples in the default graph, some will use all triples in all named graphs.
+
+- `ngraphs/` : These queries only work on named graphs
+
+
+## Requirements
+
+These migration scripts are meant to be run using the open source `onto_tool`
+program. Information about onto_tool and how to install it, is available at
+[PyPi](https://pypi.org/project/onto-tool).
+
+## Run on local files
+
+> Note: A known limitation of `onto_tool` is that it does not support named graphs when run against local files. It does support named graphs when run against a SPARQL endpoint.
+
+1. Starting in this directory, either place source data files in the `./input/` directory or point the script at the location of your data via `-v input` flag (see example below). See the onto_tool documentation for which file formats are supported.
+
+   > * The `migrate_local.yaml` file currently looks in the input directory for `*.owl` and `*.ttl` files. If other formats are supported and you plan to use them, you will need to update the yaml.
+   > * The script will only transform RDF data files at the top level of the input directory, and will not recursively descend into sub-directories. Invoke the script multiple times with different directories specified via the `-v input` flag as needed.
+
+2. Execute the following command for the default `./input` director:
+
+   ```shell
+   onto_tool bundle migrate_local.yaml
+   ```
+
+   or with a custom input directory:
+
+   ```shell
+   onto_tool bundle -v input <directory of RDF data> migrate_local.yaml
+   ```
+
+3. `onto_tool` will output to STDOUT, you should see something like the following:
+
+        INFO:root:Rename properties in named graphs.
+        INFO:root:Replace address classes in named graphs.
+        INFO:root:Replace properties with inverses in named graphs.
+        INFO:root:Use new gist:offers property in named graphs (script 1).
+        INFO:root:Use new gist:offers property in named graphs (script 2).
+        INFO:root:Rename properties in named graphs.
+        INFO:root:Replace address classes in named graphs.
+        INFO:root:Replace properties with inverses in named graphs.
+        INFO:root:Use new gist:offers property in named graphs (script 1).
+        INFO:root:Use new gist:offers property in named graphs (script 2).
+        INFO:root:Check the named graphs for other items that should be reviewed.
+        INFO:root:Check named graphs for other items that should be reviewed.
+
+   - Output files will be created in the `./output/` directory. The location can be overriden by specifying `-v output <existing directory for output>`.
+
+   - Report files will be created in the `./reports/` directory. The location can be overriden by specifying `-v report <existing directory for report>`. 
+
+## Run Against SPARQL Endpoint
+
+You will need to tell `onto_tool` the URL of your SPARQL endpoint. You can do that
+by editing the `migration_endpoint.yaml` file, or you can put it into the command
+line execution like this:
+
+> Note: Use your own values in place of `<...>`
+
+```shell
+onto_tool bundle -v user <USER> -v password <PWD>
+                 -v endpoint <ENDPOINT-URI>
+                 [ -v update_endpoint <UPDATE-URI> ]
+                 -v report <REPORT-DIR> migrate_endpoint.yaml
+```
+
+## Examples:
+
+- renameProperties replaces `gist:isGeographicallyContainedIn` with `gist:isGeoContainedIn`
+- replaceAddressClasses replaces `gist:EmailAddress` with `gist:ElectronicAddress`
+- replaceAddressClasses replaces `gist:StreetAddress` with `gist:PhysicalAddress`
+
+The different types and uses of addresses can be modeled as categories; see [the address migration documentation](./AddressMigration.md) as well as the [full documentation of the new address model](../../docs/models/AddressGuidance.md).
+
+- replacePropertiesWithInverses replaces `gist:hasPart` with `gist:isPartOf`
+- useOffersProperty (scripts 1 and 2) replaces `gist:hasPart` with `gist:offers` in the context of an offer
+- useOffersProperty (scripts 3 and 4) replaces `gist:isPartOf` with `gist:offers` in the context of an offer
+
+When converting data about offers, the offer and any sub-offer must belong to a the `gist:Offer` class or a subclass of it for the script to recognize the thing being offered.
+
+The examples above are not a complete description of each script; read the scripts to see the complete list of changes they make to the data.
+
+## Notes
+
+- read the scripts to see the complete list of changes they make to the data (the examples above are not comprehensive).
+- renameProperties, replaceAddressClasses, and replacePropertiesWithInverses remove classes and properties that were deprecated in release 12, i.e. they perform data conversion necessary to conform to gist 13.
+- useOffersProperty is optional for conformance with gist 13
+- be sure to update all artifacts such as data ingestion, queries, forms, documentation, etc. along with converting the data
+- for data conversion of magnitudes and units of measure, see the README file in the uom_queries directory

+# Unit of Measure data migration queries
+
+Follow the guidance in the slide deck uomDataMigration.pptx in the migration/v13.0 directory.
+
+There is a set of queries to explore the existing data, and other queries to perform the migration.
+
+Most of the data migration queries have to be customized per-Enterprise. 
+
+Since the conversion steps are rather extensive, you might want to run them in stages.
+
+If desired, you can create a yaml file for each stage of your data migraion (using the existing yaml files for non-uom files as a guide).
+
+The data migration queries are all designed to migrate data in named graphs; modify the queries as needed to make changes in the default graph.
