No plugin-imposed archive-size cap
MigrateNest does not refuse an archive because it crosses a paid megabyte threshold. This does not remove infrastructure limits.
Limits that still matter
- free disk space and inode quotas;
- PHP memory and execution windows;
- web-server and reverse-proxy limits;
- filesystem permissions;
- CPU throttling and remote-service timeouts.
Chunked upload and time-budgeted work reduce dependence on one long request. Preflight checks should be resolved before packaging or restore.
