Migration Strategy

From Current RPCF to CRPCF

  1. Assessment Phase (Month 1)
    • Inventory existing plugins and dependencies
    • Identify security requirements and compliance needs
    • Evaluate container orchestration platforms
  2. Preparation Phase (Months 1-2)
    • Establish code signing infrastructure
    • Deploy CRPCF infrastructure in parallel
    • Create migration tooling and scripts
  3. Pilot Migration (Month 3)
    • Select low-risk plugins for initial migration
    • Sign and containerize pilot plugins
    • Validate functionality and performance
  4. Gradual Rollout (Months 4-6)
    • Migrate plugins in waves based on criticality
    • Monitor performance and security metrics
    • Provide user training and support
  5. Full Cutover (Month 6)
    • Complete migration of all plugins
    • Decommission legacy RPCF infrastructure
    • Establish ongoing operations procedures

Backward Compatibility

public class LegacyRPCFAdapter : IPluginClassFactory<IPluginClass>
{
    private readonly IContainerizedPluginOrchestrator _orchestrator;
    
    public async Task<IPluginClass> GetInstanceAsync(
        NamespaceString moduleName, 
        IdentifierString name)
    {
        // Translate legacy calls to containerized execution
        var pluginId = new PluginIdentifier(moduleName, name);
        var container = await _orchestrator.GetOrCreateContainerAsync(pluginId);
        
        return new ContainerizedPluginProxy(container, _orchestrator);
    }
