build Migration considerations

• Imports from the old `openerp.osv` namespace: renamed to `odoo` since Odoo 10.0. migration-openerp-import · source
• Imports from the old `openerp.osv` namespace: renamed to `odoo` since Odoo 10.0. migration-openerp-import · source
• For a target of Odoo 10.0+: use the `__manifest__.py` manifest name instead of `__openerp__.py`. The filename alone does not establish module age or compatibility. migration-openerp-manifest · source
• CrmLead2opportunityPartner — Class 'CrmLead2opportunityPartner' still inherits from the old-style `osv.osv_memory` API: rewrite it against `models.Model`/`models.TransientModel`/`models.AbstractModel` - the old `osv`/`orm` API was removed entirely in modern Odoo. migration-old-api-base · source
• RrmLead — Class 'RrmLead' still inherits from the old-style `osv.osv` API: rewrite it against `models.Model`/`models.TransientModel`/`models.AbstractModel` - the old `osv`/`orm` API was removed entirely in modern Odoo. migration-old-api-base · source
• RrmLead — Class 'RrmLead' declares `_columns` as a plain dict: old-style field/default declarations, replace with `fields.X(...)` class attributes and `default=`. migration-old-style-fields · source

Migration review checklist, not a compatibility verdict. No target version is selected: apply version-specific advice only when migrating to that version or later.
