UPGRADE GUIDE
----------------
Semantic Versioning System
-----------------------------
OrientDB uses the Semantic Versioning System (http://semver.org) where given a version number MAJOR.MINOR.PATCH,
increment the:
- MAJOR version when you make incompatible API changes,
- MINOR version when you add functionality in a backwards-compatible manner
- PATCH version when you make backwards-compatible bug fixes.
So between PATCH versions the compatibility is assured (example 1.4.0 -> 1.4.1). Between MINOR and MAJOR versions you
could export and re-import the database. See below in the column "Database":
Compatibility Matrix
---------------------------
+--------+-------+--------------------------------------------+-----------+----------+----------+
| | | API | | BINARY | HTTP |
| FROM | TO |--------------------------------------------+ DATABASE | NETWORK | NETWORK |
| | | Blueprints | Document | Object | Nat.Graph | | PROTOCOL | PROTOCOL |
+--------+-------+------------+----------+--------+-----------+-----------+----------+----------+
| 1.4.x | 1.5.x | Changed | OK | OK | OK | Automatic | 16, 17 | 10 |
| | | v. 2.4.x | | | | | | |
+--------+-------+------------+----------+--------+-----------+-----------+----------+----------+
| 1.3.x | 1.4.x | Changed | OK | OK | OK | Automatic | 14, 15 | n.a. |
| | | v. 2.3.x | | | | | | |
+--------+-------+------------+----------+--------+-----------+-----------+----------+----------+
| 1.2.x | 1.3.x | Changed | OK | OK | OK | Export & | 12, 13 | n.a. |

Migrate from LOCAL storage engine to PLOCAL
---------------------------------------------
1) Open a new shell (Linux/Mac) or a Command Prompt (Windows)
2) export the database using the console. Example by exporting the database under /temp/db:
> bin/console.sh (or bin/console.bat under Windows)
orientdb> connect database local:/temp/db admin admin
orientdb> export database /temp/db.json.gzip
orientdb> disconnect
3) now always in the console create a new database using the "plocal" engine:
a) on a local filesystem:
orientdb> create database plocal:/temp/newdb admin admin plocal graph
b) on a remote server (use the server's credentials to access):
orientdb> create database remote:localhost/newdb root password plocal graph
4) now always in the console import the old database in the new one:
orientdb> import database /temp/db.json.gzip -preserveClusterIDs=true
orientdb> quit
API history
----------------------
- 1.4.x Blueprints becomes the new standard API for the Graph Database. All the GraphDB APIs are deprecated
