# Introduction
Currently preparing the `UpgradeCommand` refactor, in this way started
by cleaning up the existing avoiding unecessary dependencies to others
services allowing easier readability and concern centralization for
upcoming refactor
The UpgradeCommand was extending up to five classes, overriding
abstracted class and so on. It was also cascade
injecting 3 services
Introducing the `WorkspaceIteratorService` that centralize the commands
set to run over a single workspace logic shared between both atomic
upgrade command call and global upgradeCommand
## Tradeoff
Duplicated `@Option` between both `UpgradeCommandRunner` and
`WorkspaceMigrationRunner`
## Before
```
UpgradeCommand
└─ extends UpgradeCommandRunner
└─ extends ActiveOrSuspendedWorkspacesMigrationCommandRunner
└─ extends WorkspacesMigrationCommandRunner (owns workspace iteration loop + ORM deps)
└─ extends MigrationCommandRunner (dry-run, verbose, error handling)
└─ extends CommandRunner (nest-commander)
```
## Now
```
UpgradeCommand
└─ extends UpgradeCommandRunner
└─ extends CommandRunner (nest-commander)
uses ─► Services (via composition)
```
## Logging management
At the moment all services are logging, in the best of the world only
the runners should be doing so
