Extends [Cloud Migration Management](../page/40063.md).

## Fields on this page

Layout controls in source order, grouped by the container they sit in. Shows: the table field a control is bound to (or its expression as written); ToolTip: the control's own, else the bound field's (marked).

| Group | Control | Shows | ToolTip |
|---|---|---|---|
| modify(CompaniesStatusText) | Companies Replication status | modifies `CompaniesStatusText` | — |
| addlast(OveralInformation) | Companies Upgrade status | `CompanyUpgradeStatusText` | Specifies the upgrade-phase status summary for all companies (separate from the replication-phase Companies Replication status above). Format: Pending: X, Started: Y, Completed: Z, Failed: W. Drill down to see per-company status. |
|  | Upgrade Error Details | `UpgradeErrorDetailsText` | Specifies the accumulated error messages and call stacks captured for failed companies during the Business Central 14 upgrade. |

## Actions

| Group | Action | ToolTip | Runs |
|---|---|---|---|
| modify(RunDataUpgrade) | RunDataUpgrade | — | modifies `RunDataUpgrade` |
| addlast(Processing) | Configure BC14 Re-implementation | Configure default re-implementation settings (modules, posting, error handling). Per-company overrides, upgrade timing, and re-implementation errors are reachable from inside. |  |
|  | BC14 Migration Errors | View the BC14 migration errors collected across all companies and migrators. | [Page 46863 "BC14 Migration Error Overview"](../page/46863.md) |
|  | Resume Business Central 14 Upgrade | Continue the Business Central 14 upgrade after a failure or interruption. If any company is Pending, the next one is dispatched. If only Failed companies remain, you are prompted to reset them to Pending and retry. |  |

## Relations

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 46858 "BC14 Migration Status Mgr."](../codeunit/46858.md) (4 calls: `RerunFailedCompanies → FilterFailedCompanies`, `ResumeBC14UpgradeAction → GetCompanyStatusCounts`, `UpdateCompanyUpgradeStatus → GetCompanyStatusCounts`, …)
- [Codeunit 46862 "BC14 Migration Orchestrator"](../codeunit/46862.md) (3 calls: `ResumeBC14UpgradeAction → DispatchNextReadyCompany`, `ResumeBC14UpgradeAction → FindLatestReplicationSummary`, `UpdateUpgradeErrorDetails → FindLatestReplicationSummary`)
- [Codeunit 46861 "BC14 Wizard"](../codeunit/46861.md) (1 call: `OnOpenPage → GetBC14MigrationEnabled`)
- [Codeunit 46875 "BC14 Migration Runner"](../codeunit/46875.md) (1 call: `RerunFailedCompanies → ContinueMigrationForCompany`)

## Across versions

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "pageextension", object_name: "BC14 Cloud Migration Mgmt Ext")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
