Your day to day

Living with the old system

For a few months you will have two places. How to manage without duplicating work or losing things.

Updated on 13/08/2026

Nobody switches systems overnight. For a few months some things will be here and some in the usual folder, and that period is where documents go missing and where people decide whether the change is real.

The rule that makes it work

Important

**New material comes in here from day one; old material comes in only when it is needed.** Without that rule you end up maintaining both places in full, which is double the work and why most transitions get abandoned.

What goes where during the overlap

SituationWhere it goesWhy
A new document arriving todayHere, alwaysIf there are exceptions, there is no rule
An old document someone consultsUploaded as it is consultedYou bring what gets used, which is little
An old document nobody touchesStays where it isBringing it adds nothing
An old document expiring soonBring it nowIt is the one you will need

How to run the period

  1. 1

    Set a cut-off date and say it out loud

    "From Monday the 3rd, whatever arrives goes here." Without a date there is no cut-off.

  2. 2

    Make the old system read-only when you can

    While both can be written to, both will be written to.

  3. 3

    Bring the expiring items first

    Insurance, certificates and contracts with end dates. They are what you will need soonest.

  4. 4

    And review after two months what has come across

    Usually 10% of the archive. That figure tells you how much of the rest was unnecessary.

Watch out

The costliest failure is not technical: it is someone still saving to the old folder "just this once". Within a month there are two truths and nobody knows which to check. If you spot that, it is more urgent than any migration.

When you can call it done

Worth knowing

The old archive need not be deleted. It can stay read-only for as long as you like: what matters is that it stops receiving new material, not that it disappears.

Can I upload everything at once?

You can, and sometimes it pays. But bringing what nobody looks at only buries what matters.

How long does the overlap last?

Weeks with a cut-off date; indefinitely without one.

What if the team resists?

It is almost always because they cannot find something. Look at that before insisting.

A real case

The situation

A team has spent four months with documents in two places and no longer knows which is right.

What you do

  1. Sets a cut-off date and makes the old folder read-only
  2. Uploads what expires this year first

What you get

Within three weeks "where is this?" stops having two answers.

The situation

For six months the old and new systems coexist and nobody knows which to check.

What you do

  1. Sets the date from which only the new one counts
  2. Leaves the old one read-only
  3. Announces the cut-off to the whole team

What you get

There stop being two truths and nobody works in the wrong place.

The situation

A document is uploaded to the old system out of habit.

What you do

  1. Closes document intake on the old one

What you get

New material lands where it should.

The situation

You search the new one and the document is in the old.

What you do

  1. Notes which period each one covers

What you get

You know where to look without trying both.

The situation

The old system is switched off with documents nobody migrated.

What you do

  1. Checks what remains before switching off

What you get

Nothing is lost along the way.

The situation

Nobody decides when the old one gets switched off.

What you do

  1. Sets a date and an owner

What you get

The overlap ends rather than lasting forever.
